Exchange 2010 OAB problem

well, I still got OAB errors in Exchange 2010.

OABGen could not generate full details for some entries in the offline address list for address list '\ xxxx

it seems there is no cure as of yet.

family friend's IBM T21 problem

This problem bugged me since last year.

The error is 0175: bad CRC1, stop POST task.

Thinkpad T21, yeah, is fine piece of art.

I told my family's friends that the BIOS chip might be fault or corrupted.

Then family friends bought a bios chip from CN.  on the top of the chip:
30L2412 rev 49, (C) IBM 00, T2602

a google search turned out this is for T23.

I started to dismantle the T21. well the bios chip is actually under the memory modules.
Intel flash
08K3976
REV 15
T5200

google search indicated this model is for T20. anyway there is little more I can do to help.

OAB and hosted exchange 2010

http://blogs.msexchange.org/silva/2008/05/22/exchange-shared-hosting-and-addressbookroots/
http://www.kortekservices.com/lyle/




I followed above articles. But I can't get OAB to work.

there is an entry addressbookroots2 in addition to addressbookroots.



my setup is Windows 2008 + Exchange 2010.



hopefully, this is not related to autodiscovery as indicated in various forums.



So far, I get OWA working and I get outlook anywhere working with outlook 2007.

Hosted Exchange 2010 - continued

here are some useful links

this link refers to generating self-created cert for outlook anywhere.

http://www.kirkouimet.com/blog/2008/06/generate-a-self-signed-certificate-in-exchange-server-2007-to-be-used-for-outlook-anywhere-on-outlook-2007/

protected object in Windows 2008

protect object from accidental deletion. you can delete it and you can't move it. the trick is to enable advanced features in view menu.

add more UPN suffixes in Windows domain

you add those UPN in active directory domain and trusts

use shadow protect Q1 2010 IT ed imaging a VM inside ESX 3.0.1

got a network license error when access the IT ed CD via network.

the trick is to put the in the vmware host, and make the host cdrom available to the VM PC. the speed is impressive.

in comparsion, someone else's script can't copy VMDK when the VM is running.

Hosted Exchange 2010

Hosted Exchange 2010, what is like? where are the tools from MS to do it? there seems no tools for Exchange 2010 as of yet.

People has done hosted exchange 2007. That's something I can refer to.

things need to separate

I followed MSFT  - Zhang's instruction
1. make sure IIS WinRM extension is installed


2. open powershell and run command : WinRM Quickconfig

3. Open IIS go to Powershell virtual directory and check that SSL in disabled and authentification is set only to Anonymous

4. Open Windows powershell modules

but I can't do
5. run Remove-PowershellVirtualDirectory command


6. run New-PowershellVirtuallirectory command

those two cmd asking for identity.
anyway, I can open the exchange 2010 EMC now.

configure sonicwall TZ100

what a nitemare. yeah my first enhanced os config.

I manually configured the rules. well that didn't work. I am told to use wizards. that worked.

I have configured standard OS on sonicwall TZ 170/180 for years. this is really a shock.

the new TZ 100 hasn't got nodes limit, more features, of course enhanced OS.

Google CN vs. Chinese rulers .... BING

Its quite a shock when I heard google's planning to leave China.
Now two week has passed. the storm is already gone or still gathering.

I would agree that the western world lead by US would be more vocal on China's dark side. As US is pulling out of Iraq so they have more energy to do so, with only the Afghan war to win or lose.

Google's 30% Chinese search market share is not bad. Baidu has 60%.

It would be hard for Google to over take Baidu as Baidu is a promoted local in China.

I dont use Baidu as I am out of China. I do rely on Google in order to complete my daily work.

If Google is ever to leave China, that will make Chinese authorities look bad. If cn-authorities feel they are threatened, they dont care about all those, but ......

As for BING, I hardly use it (sorry microsoft). I wonder MS setup a cert path to verify someone is a BING professional.

installed firefox 3.6 and Chrome on my x64 W7 ultimate

I finnaly had enough with the IE8 crashing on this notebook. so Chrome and Firefox are now downloaded and loaded.

My problem with firefox and chrome is that those two are not always working with some web sites.

space routers on satellite

well my IE8 crashed again, I have to re-type this.

I happen to notice some news about CISCO doing some space routers with DoD.

that shouldn't something new. as satellite communication has been around for ages.

so P-2-P satellite communiaction should make sense.

It is easier for EM waves to travel across the space than submarine.

Fibre is hard to beat, but laying fibre across continent is harder than launching a satellite

Microsoft allied with HP for Cloud computing? and Intel allied with HP for processor?

MS is selling its cloud system azure based on HP platform. will this Win-HiP crash all cloud computing opponents?
like the wintel in the old NT4 days?

Yeah we know intel teamed with HP doing itanium for ages.

It seems HP will go big.

my continued nitemare with that generic P4-PC

its an ECS 865pe-A v2 mb. replaced memory b4 X'mas. still give me blue screen 0x00000050, 0x00000024 errors. MS error feedback suggests that has something to do with drivers/anti-virus.
I think its mainboard. updated BIOS to the 2005 version. no luck. the client said it crashed oftern in skype.
for me, it would intermittenly crash doing Malware scan, or MS essential security scan.
changed memory twice, still no luck.
use Hiren 10.1 CD to test it, it passed the memory (except one - troubleshooter?), mb, hdd, cpu.
I have since disconnected one cdrom to save power for the 300W P/S.

HP probook 4710s

this is a notebook with a huge footprint. ideally for accountant.
anyway I feel it is sorta of slow. maybe because the hard drive is WDC WD3200BERT. according to their website the spin is 5400RPM.

Hiren BootCD ... testing tools

http://www.hirensbootcd.net/advertise.html

I got a P4-PC back, reboot/freezing randomly. now I need a test CD.

windows 2003 (cn) cpu sometimes 100%

well, its wasn't sometimes. this is my home installation. I had this problem for years.

the problem occurs when i open about 10 ie windows. pain in the  a@ss

install adobe 9.3

adobe reader disappeared from a client's PC. the customer got a problem to download from internet.

so It's my chance to make some money. anoyingly, I can't download the adobe PDF reder installation files for sometime now. I have to install on another PC in order to get the installation files

upgrade Office 2007 basic with Access 2007 upgrade

Access 2007 upgrade can upgrade Office 2007 basic which includes Outlook, Excel, and word.

the gotcha is I installed Office 2007 OEM in default settings, that was the oem version Access 2007 installed as well.

so to avoid conflict, remove all access from the PC. re-install access 2007 upgrade

XP slipstream , Windows 2000 upgrade re-visited

now I got another chance to upgrade a windows 2000 PC. this time I need do it right.
the PC is a generic sis chipset based Celeron 3.0GHZ.

I have a Volume licensed XP CD, I slipstreamed to SP3. But the new VL-XP CD wont accept the original keys for some reason.

so I put VL-XP w/sp2 cd in, start the upgrade process, and choose get updates from internet. still no luck, the system keeps rebooting, even if I uninstalled anti-virus, diskkeeper.

in despair, I put the the XP OEM CD (w/sp3), it is all going well.

DGE-530T driver download

its quite annoying to browse Dlink website, Celeron 3.0GHZ cpu usage sometimes goes to 90%. Dlink website is heavily flashed?

corrupted nero

after writing 4 corrupted CD-Rs, and a swap of DVD/RW, I realized that the nero is corrupted on one of my work PCs. annoying.

remove nero. use ultraiso created SP IT Q1 2010 images

failed to archive files to DVD

one reason I would say I haven't got enough room on hard drives to buffer. one drive got about 4GB free, the other about 1.9 GB free.

use different signatures in outlook 2007 and outlook 2003

of course, you need create multiple signatures first in outlook.

in outlook 2007, its simple, there is a big button in the menu signatures, click on that you can switch to a list of available signatures.

in outlook 2003, need a signature to be the default one, then right-click on the signature in outlook, then you can switch to other signatures.

image a computer hard drives over to another computer

I know some computer will never wake up after the long holiday.

one of a client's important workstation failed to start, the hard drive light seemed always on. from past experience I knew one of the hard drive wasn't starting.

then take an image of another PC (Win-XP) with similar functionality.. well my ShadowProtect IT edition expired Q4 2009. luckily I have a Shadow Protect 3.3 CD. That saved the day. interestingly the local ShadowProect distributor wanted to send a copy of Oct 2009 IT edition. I wonder that will make any difference.

I started the process of elimination, 2 of the 3 internal hard drives not starting properly. ironically this faulty system started perfectly today. but after I run scandisk, the whole thing crashed again.

put in a new hard drive, I have restore the image to to this drive and remaining one. the first shadow protect boot crashed, I have to un-plug the old remianing hard drive from the on-board gigbyte raid controller. then restore the boot-image to the new hard drive.

behold my breath, now the image is successfully copied over. the Win-XP is starting, pop in the motherboard cd to load all the drivers. P4-3.2GHZ, very old PC.

two HP nx6120 freezing

two HP nx6120 almost the same problem, run BIOS diagnostics, seems fine.
decided to reload everything from scratch. also advised if the same things happens again, it must be the mainboard. not worth any more work on that.

there are discussions on HP forums about this.

What is a MS 2008 R2 foundation server?

well the comparision link is here

http://www.microsoft.com/windowsserver2008/en/us/r2-differentiated-features.aspx

according to the list, foundation server can't do failover clustering, of course that's an enterprise feature.
it can't do DirectAccess Management,
it can't be BranchCache Hosted Server,surprisingly, standard edition don't have this either.


not too sure how much cheaper foundation server than the standard server.

the price difference will make more people choose the foundation over standard.

USB 3.0 demoed at CES 2010

I happen to spot a Youtube footage about USB 3 speed. It is very impresive, very fast.
its 10 times faster than USB 2.0, low CPU usage.
their test show about 216MB/s copying 1GB file. its about alright as I noticed in my daily work USB2 is about 1GB per minute. that is USB 2 is about 20~67 MB/s over shadowProtect sessions.

Make more web parts available in the portal MOSS 2007

yeah, Moss 2007 installed. But the content query web part is still not available in the edit page.

I tried to enable features in site settings, well, it is not there.

I had to go up one level to enable the features in the site collections first. then enable in site settings again.

I noticed the web parts numbers avaliable grow from 17 to 55.

post Moss 2007 installation configuration

after the Moss2007 install, a new wizard started another round. basically update the current two databases - one is the configuration, another is content database. 
some services cannot be run because my Moss is in standalone mode not in a domain.

But when I tried to open the web site, surprisingly I got an error in red  like

/ runtime error

need change web.config
remote mode off/on

also there is an extra line appsetting/ > ... just delete this un-matched line. \

then the web site sprung to life, ... well bit slower than before

install MOSS 2007

had enough with missing features in WSS3.0.

So I installed MOSS 2007 on the WSS3.0 box.

chuck in MOSS 2007 DVD/CD into the box, click install. have to put key in because its not free.

then choose full install instead of front-end.

content query web part is MOSS only

couldn't find CQWP in my WSS3.0. alas, its another MOSS feature

Exchange 2010 UM technet lab

Exchange 2010 UM technet lab ...tried twice, first part is fine. But I couldn't finish the phone validation bits.

when I tried to post a feed back, got a internal error 500. the message is error=failed to get device allocation. I wonder real phone device is needed to complete the lab.

anyway, I would not complain since its free. virtual labs have improved lot in the Exchange 2010 series, that may be due to my home DSL upgraded.

IE8 and Technet exchange 2010 virtual labs

I can't get IE8 working with Technet 2010 virtual lab.
however, IE6 in W7 XP mode works, so I can complete a couple of the E2010 virtual labs.

Branch Cache (MS Elearning)

BranchCache operates in one of the following two modes, based on the cache location:




Hosted Cache. The Hosted Cache mode operates by deploying a computer that is running Windows Server 2008 R2 as a host in the branch office. Client computers are configured with the fully qualified domain name (FQDN) of the host computer so that they can retrieve content from the Hosted Cache when available. If the content is not available in the Hosted Cache, the content is retrieved from the content server by using a WAN link and then provided to the Hosted Cache, so that the subsequent client requests can get it from there.

Distributed Cache. You can configure BranchCache in the Distributed Cache mode for small branch offices. In this mode, local Windows 7 clients keep a copy of the content and make it available to other authorized clients that request the same data. This eliminates the need to have a server in the branch office. However, unlike the Hosted Cache mode, this configuration works across a single subnet only. In addition, clients that hibernate or disconnect from the network will not be able to provide content to other requesting clients.

Direct Access

DirectAccess provides consistent connectivity experience whether the client computer is local or remote. This allows users to focus more on productivity and less on connectivity options and process. This consistency can reduce training costs for users and result in fewer support incidents (MS Elearning)

yeah, this sounds like outlook anywhere.

there is no download for VS 2005 express any more. no download link on MS website, only 2010. but VS2008 express is on some third party site.

Active Directory Domain Services Enhancements in Windows Server 2008 R2

In Windows Server 2008 R2, the Active Directory Domain Services (AD DS) role includes many new features, such as Active Directory Recycle Bin, Active Directory Web Services, and Offline Domain Join. You can configure these features to improve Active Directory manageability, supportability, and performance. AD DS in Windows Server 2008 R2 includes the Active Directory Administrative Center, a new task-oriented administrative tool for managing Active Directory. You can use the graphical user interface (GUI) features in Active Directory Administrative Center to improve your productivity and efficiency in performing Active Directory management tasks.

SQL Slammer - re-visited

well, SQL slammer is pretty much still alive on the internet. one guy configured a small biz customer's router and set the dmz host to be the local apps server. that Apps server runs a sql 2000 version of MSDE. 

they started to have network problems, the server started to freeze, and the internet DSL router led flashes like hell.

this baffled me a couple of times as I reckon this is very old worm. But the bitter lession is "Don't assume anything".

Never expose MSDE 2000 to the internet. within hours, internet worms will find it, spam it and trash it.

CAT 5 Cabling re-visited

uncle Bill moved to a swanky big house. the house was cabled with CAT5, but not much labeling.

all the cables go to a closet in the laundry. but there is no patch panel on this side, these is a small patch panel for telephone leads ( m-block?).

on the walls in those rooms, those sockets are not labeled. peel off the wall cover, its labeled inside. well, still can't tell which is which on the otherside.

The manager told me to use a multi-meter to measure it. To do that, cut a CAT 5 lead, and short w/Green and green, as well as W/Orange and Orange. the idea is to measure the leads on the other side.

there are about more than one dozen cables in what should be a patch panel area. to identify further, I used a cable detector which will buzz a noise louder with a match. But I found it was less effective when some phone lines are in shaunt.

wall socket: need pull out a little bit to identfy it is is T568A or B cabling. I would say some old T568 terminating sockets only type A or B. the new ones are dual-colored, can do either A or B depending which color code you using. needless to say you need use one to match the one on the wall. one annoying for me is that I often mix up which slice is which when I punch those wires like w/G or G. so A cable tester is used to test the cabling.

cabling standard T568A and T568B: the difference is green pairs and orange pairs are transposed.

T568B
1    W/ORANGE
2    ORANGE
3    W/GREEN
4    BLUE

new power saving feature in W2008 R2 (source: Elearning)

Windows Server 2008 R2 introduces significant advancements in server power management capabilities. The Processor Power Management (PPM) engine in Windows Server 2008 R2 is rewritten and improved, and there are additional power-management Group Policy settings that help to fine-tune the processor’s speed and power consumption to match current demands. New parameters for PPM further improve the power efficiency. You can use features such as Core Parking, reduced processor power consumption, centralized storage, and Intelligent Timer Tick Distribution in virtualization scenarios to maximize the power efficiency of virtualized environments and physical systems.




Windows Server 2008 R2 reduces processor power consumption in server computers with multicore processors by using the Core Parking feature. The Core Parking feature enables Windows Server 2008 R2 to reduce multicore processor power consumption by consolidating processing onto fewer processor cores and suspending the inactive cores. The workload of every logical core in a server is tracked relative to all the others. The workloads of cores that are not being fully utilized can be suspended, and these workloads are then shifted to alternate cores. Keeping the unutilized cores in an idle state reduces the system power consumption. When additional processing power is required, the system activates the idle processor cores to handle the increased processing requirements.



Windows Server 2008 R2 adjusts the processor speed by using Advanced Configuration and Power Interface (ACPI) "P-states" of processors and reduces server power consumption. ACPI “P-states” are the processor performance states within the ACPI specification. Depending on the processor architecture, Windows Server 2008 R2 can adjust the P-states of individual processors and provide control over power consumption.



Another strategy for reducing power used by individual servers is to centralize their storage by using a storage area network (SAN), which has a higher storage-capacity-to-power-consumption ratio than a typical server. SAN makes more efficient use of the available disk space, because any server can have access to the available storage on SAN. Windows Server 2008 R2 greatly improves access to storage on SANs and supports booting from a SAN, which eliminates the need for local hard disks in the individual server computers. As a result, power consumption decreases.



Windows Server 2008 R2 introduces Intelligent Timer Tick Distribution or Tick Skipping. This feature extends processor idle states or deep “C-states” by not activating the CPU unnecessarily, thus saving power. Only one processor handles the periodic system timer tick; other processors are signaled only when necessary. The amount of background work that is performed by the operating system is reduced in Windows Server 2008 R2. This allows processors to better utilize the deep “C-states”, in which the processor consumes very little energy, but requires time to return to an operational state

Windows 2008 R2 enhancements (source: MS Elearning)

Windows Server 2008 R2 reduces the effort for managing physical and virtual servers by providing enhanced management consoles and automation for repetitive day-to-day administrative tasks. You can use Server Manager in Windows Server 2008 R2 to manage local and remote systems, integrate BPA, and improve integration with other management consoles. Windows Server 2008 R2 includes File Classification Infrastructure (FCI), which automates file management tasks. In addition, Windows Server 2008 R2 has many enhancements to Power Management and Windows Server Backup. These enhancements provide better energy efficiency and performance by reducing power consumption and lowering overhead costs. Windows Server 2008 R2 also has Windows PowerShell 2.0, which integrates with the .NET Framework and provides a command-line environment to control and automate the administration of the Windows operating system and the applications that run on Windows

blue screen netr70.sys and linksys WUSB54G REV 4

yeah blue screen while I am browsing the internet... netr70.sys.

just done a live chat with a linsys online agent, I am told no driver yet for W7. I must be using the vista driver or XP driver from the production CD.

user profile corruption: outlook not working properly

user profile corruption: outlook not working properly  ...

again, rebuild outlook cache file (exchange 2003 client) ... no luck...

logon as a different user, outlook is fine..

rebuild this user's whole profile

user profile corruption: screen freezing

user profile corruption: screen freezing ... logon as a different user is fine...

so it pays to test login as a different user before someone trying to replace the switch because the nic led flashing too fast.

user profile corruption: cannot print

a user can't print properly. log-on as another test user, its all good.
so have to re-build that users profile to fix the problem

change time/clock on Sub-sites

well ... time & clock still not right in sub-sites
goto site-settings ... site administration - regional settings

fantastic 40 templates for SharePoint server 3.00

re-visit this topic

application core templates need be installed first

20 WSP application templates, this will appear as applications

20 STP site templates, installed via GUI site galleries interface ... when you created site using templates you will see a custom tab. But I could not find the upload multi-templates option, have to upload one by one.

sharepoint website editor

notepad ( or a html editor)
SharePoint Designer 2007
Visual Studio 2005/2008

SharePoint Designer 2007 seems the best tool for Now.

delete a top link in a WSS 3.0 site

click Home at top left .... then top right ... site actions .... site settings .... look and feel ... top link bar ... select and click on the top link you want to delete ... click on delete ... ok

SharePoint site clock/time not correct

not sure why is that. have to goto site sittings ---> regional settings ----> locale ... change from English (US) to local english.

modify a wrong link posted at WSS 3.0 site

dunno what happened to me, I had bit a problem to change it. it is very simple. just click on "links", it will bring up the links page, then I can modify it to my hearts contente.

yeah, I am in writing mode W2008 vs W2008 R2

yeah, I am in writing mode

System Requirements for Windows Server 2008 R2 (source: MS-Elearning)

Windows Server 2008 R2 has system requirements similar to Windows Server 2008, but Windows Server 2008 R2 runs only on 64-bit processors. Although Windows Server 2008 R2 can be installed on a computer with 512 megabytes (MB) of RAM, the computer can use up to 8 gigabytes (GB) for Windows Server 2008 R2 Foundation, 32 GB for Windows Web Server 2008 R2 or Windows Server 2008 R2 Standard, and up to 2 terabytes for Windows Server 2008 R2 Enterprise or Windows Server 2008 R2 Datacenter. System requirements vary between Full Installation and Server Core installation. You can perform an upgrade to Windows Server 2008 R2 from Windows Server 2003 SP2 or a newer server operating system, or you can perform a clean installation of Windows Server 2008 R2. A clean installation is the only option if the previous server is running on a 32-bit processor.




A Windows Server 2008 R2 upgrade is possible from previous 64-bit server operating systems such as Windows Server 2003 R2, Windows Server 2008 SP2, and Windows Server 2008. It does not support upgrades from older operating systems and cross-architecture—32-bit to 64-bit; cross-language—German to English; and cross-edition—Windows Server 2008 Enterprise to Windows Server 2008 R2 Standard. It also does not support upgrade from Itanium-based systems.



Windows Server 2008 R2 expands CPU support to run up to 256 logical processors in a single server. Hyper-V in Windows Server 2008 R2 can access up to 64 logical CPUs on host computers. This can help in increasing virtual machine consolidation ratios per physical host. In addition, Hyper-V supports the latest CPU technologies and advanced storage technologies, including storage area network (SAN) management and solid state devices. Windows Server 2008 R2 can boot from SAN or VHD.
