server 2003 domain to server 2016 domain migration

it can still be done

domain and forest level need be raised to 2003 first

got a problem sysvol / netlogon not showing up on the new DC

so, before migration, check dns is valid

that ghost problem bugged me again --- setup WID on a windows 2016 domain controller

when setup a PPTP server on a windows 2016 DC

I had that WID not starting issue again

the trick is to change WID to auto start rather than manual

I thought service set to manual start will start if needed

but in this case, not true, cause a problem and lots of frustration
