Exchange 2003 LDAB Bind Error Event 8026

We have an Exchange 2003 environment and I've noticed an error:

LDAP Bind was unsuccessful on directory SERVER1.domain.loc for distinguished name ''. Directory returned error:[0x51] Server Down.    

I'm not surprised by these errors, this server (DC server) failed about a year ago and I "thought" we cleaned up all the references of it. I've searched through DNS and our AD structure but can't find the reference... Where is this reference and how can I get rid of it?

I'm preparing for a migration to 2010 and I want to ensure all the server is running optimally...

Thanks in advance!

Did you do a metadatacleanup of the failed DC?

Is this error just on the exchange sever? Can you run a DCDIAG and repadmin /showrepl to make sure they are both error free.

If it is just exchange I would check the DSAccess setting on the exchange server.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

As KenMcF has pointed out, check your Exchange DSAccess settings to see if the old DC has been manually entered there.

Was my answer correct? Was the old Dc manually entered in the DsAccess settings?
