my black Friday -- a day of restore and recovery of BSODs

my black Friday -- a day of restore and recovery of BSODs

the company I work for decided to move Xen VMs to Windows 2016 Hyper-V

the current Xen host was installed about a few month ago  - Xen 5.6 or 6.x

the backup software is StorageCraft 's shadow protect

so I started to restore backup images today

the speed is not bad, its about 1GB per minute

the servers are windows 2008 as DC and a windows 2003 terminal server

1/ blue screen of death --- on the windows 2008 DC

the W 2008 crashed to bluescreen with active directory errors, I have to boot the server to directorty recovery mode to do a ese util repair on the ntds.dit

so you need DSRM password handy, as I installed this server 6 years ago, my typical habitual password worked

2/ bluescreen of death on the restored windows 2003 server,
the windows 2003 crashed to blue screen, the error is like c*.dll error, I blogged this error in 2015. so I did the fix again, the fix is to copy 5 files from ddlcache folder.

ntdll.dll and 4 nt*.exe files, very bizare because current ones got 2007 timestamp, but the dll cache got 2015 time stamp


one thing worth notice is that I dont see insert integration services disc in the action manual as probably those two servers are legacy servers

I have to manually add a lagecy network card to the w2003 server

w2003 still supported on hyper-v 2016 , but I dont see fully supported

3/ continue to recover
then the dhcp server wont start
tried to repair the dhcp.mdb , got error, delete it, and start the dhcp server again, ending up with re-creating dhcp configuration
