Hi

I'm have an DC issue that I'm looking for help to solve.

Our 2nd Win2k DC crashed, it where also running Exch2k.
The problem is that before our technician called me they
had reinstalled the OS in the server and promoted it to
2nd DC again with the same computername and registered a
new computer account.

after that, they tried to restore all local drives and
system state from backup in "OS running mode" and guess
what... yes, it was a bad idea... :/

Instead we did reinstalled the OS and in DS repair mode
restored all local drives and system state. this time
everything went well... ACCEPT that we now have problem
with synchronisation with the other DC in our domain.

Yeah, I know about the changed SID's and the change of USN.

Can anyone please sort things out for me so that I can get
back on track? I need the Exch2k to run in the morning.

Looking forward an quick answere :)

Best regards
Peter
 
Hi Peter-

You will need to remove all references to the server that has been
reinstalled and repromoted from the domain pre the article below.

Once that is done, put a new install of Windows on the domain controller
that has had the problems.

Then, after this change has had a chance to replicate throughout your
enterprise, you can repromote that server into the domain as a domain
controller of the same name.

Please repost if you have any questions or concerns.
