DC on Exchange Server

One DC was crashed and we have already recreate the DC and granted to the domain again.

Under Exchange, it had removed the crashed DC but it doesn't add it back even though the DC is up and running now. This DC is a global catalog and DNS has been binded to this DC.

Is it possible to analysis on Exchange why it doesn't take up this DC in Exchange ? Tks

It's not recommended to add the DC role to an exchange server unless it's a SBS server.

Assuming you have Ex2010, restart the Exchange Active Directory Topology Service on the Exchange Server.

Are you sure the DC is back up and running correctly?

How did you recover the DC? Or did you just rebuild a new DC and gave it the same name and IP?

Are NETLOGON / SYSVOL shares available on the recovered DC? What happens if you run IPCONFIG /REGISTERDNS from the DC and wait a good 15 minutes?

Also, try running DCDIAG from command line on the DC. Anything happen?

2 x Exchange 2010 running in DAG on Window 2008R2.

2 x Window 2008R2 DC + 1 x Window 2003 DC.

One DC is crashed and rebuilt with same name and IP address. Also check the netlogon and sysvol is not on the new created DC...

Is that the problem ? How to fix it ?

Yea if SYSVOL and NETLOGON are missing then the DC is not functioning correctly. Was this a fresh install to rebuild this server? If so, before you gave it the same name and IP, did you do a proper cleanup of the old DC out of Active Directory? Metadata cleanup etc.

Safest option may be to demote, give it a new name and IP and them promote back.

What Is Threat Intelligence?

Threat intelligence is often discussed, but rarely understood. Starting with a precise definition, along with clear business goals, is essential.

We haven't done Meata cleanup. Simply depromote the old DC. Reinstall a fresh copy on another computer and promot it again.

We also install another new DC and we encounter the same problem, sysvol and netlogon not appears...

Awesome. So as soon as you did this, the DC showed up on the Exchange server right?

I disagree with the moderation here. ID: 40016580 prompted the original poster to look if SYSVOL was present or not. At that point it was determined it was not present. Which led to the solution.
