Hi all,
after adding my the Global Catalog server role to my new AD server and removing the GC from my old DC I can see the following error message in directory services events:
"Active Directory was unable to establish a connection with the global catalog.
Additional Data
Error value:
1355 The specified domain either does not exist or could not be contacted.
Internal ID:
3200cf3"
None of the clients in my network can logon anymore. That means my problem is really severe and I need help urgently. The situation is as follows.
I migrated our Active Directory Domain from Windows 2003 to Windows 2008 R2. I moved all roles to the new server which worked without problems. DNS also was configured properly. During my tests I found out that I also need to move the Global Catalog to the new server. So I checked the NTDS properties for the new server in Active Directory Sites and Services and that the option "Global Catalog" was enabled already. This was the final step to demote and remove my old Windows 2003 Domain Controller, so I unchecked"Global Catalog" in the NTDS Settings of my old DC and confirmed the warning message that no new GC was found in the domain (I know this was a mistake now!). I removed the GC role from my old server. Before that I made sure that the new server has become a GC by checking the GC column under the domain controller group in Active Directory Users & Computers.
After disabling the GC checkbox for the old server both DCs started logging the error messages as above.
The DCDiag results showed up that the DCs still were advertising and have not become a GC yet. I think the reason for that was a orphaned sub domain which was removed manually a fews months ago.
Re-enableing the GC role for the old server did not help. No user can login in the moment.
Is there any way to fix the GC role?
Thanks
Martin
