DCDiag issue 1

[irbk]

While troubleshooting a different issue, I ran across this error during a DCDIAG /C operation

Starting test: VerifyEnterpriseReferences
         The following problems were found while verifying various important DN
         references.  Note, that  these problems can be reported because of
         latency in replication.  So follow up to resolve the following
         problems, only if the same problem is reported on all DCs for a given
         domain or if  the problem persists after replication has had
         reasonable time to replicate changes.

I looked at Q312862 but couldn't find anything that seemed to point me towards a solution. Suggestions?

Went into ADSIedit. Made sure the naming context was "Domain" by right clicking on the top level in ADSIedit and selecting settings. On a server you select "Domain" from another system running ADSIedit it's "Default Naming context". From there you just need to read the name backwards to find the location so

CN=POSTOFFICE,CN=Domain System Volume (SYSVOL share),CN=File Replication Service,CN=System,DC=tnamain,DC=com

turns into

DC=com, DC=tnamain, CN=System, CN=File Replication Service, CN=Domain System Volume (SYSVOL share),CN=POSTOFFICE

After finally finding the erroneous entry I was able to delete it and the error is gone. I'm not even sure where this thing came from. We may have had a system called postoffice at one point but it would have been a temporary server that we used while we were migrating to Exchange 2003, not a domain controller, so how it ended up in the File Replication Service settings I've no idea.
