Please bear with me as I try to explain this...
I have an old 2003 domain controller named CONPSRVF1-R2 that I had a consultant demote from our domain about three months ago. The FSMO roles were moved to DC "NPPDVMDC1-12" which is a virtual server. I have another DC that is a physical server named "NPPDDC2-08".
I've been having these weird group policy issues lately, and last week I found that on both of my existing DC's the File Replication Services were getting the following error (Event ID; 13508) which explains the weird and inconsistent group policy problems I've been having:
The File Replication Service is having trouble enabling replication from CONPSRVF1-R2 to NPPDDC2-08 for c:\windows\sysvol\domain using the DNS name conpsrvf1-r2.domainname.local. FRS will keep retrying.
Following are some of the reasons you would see this warning.
[1] FRS can not correctly resolve the DNS name conpsrvf1-r2.domainname.local from this computer.
[2] FRS is not running on conpsrvf1-r2.domainname.local.
[3] The topology information in the Active Directory Domain Services for this replica has not yet replicated to all the Domain Controllers.
This event log message will appear once per connection, After the problem is fixed you will see another event log message indicating that the connection has been established.
For some reason the old 2003 DC (CONPSRVF1-R2) is still showing up in AD. So, today I followed the instructions in the How-To to manually remove the old DC:
Step 6 in the How-To refers to cleaning up DNS. I did this. However, I am stuck. I have an entry called "_msdcs" directly under my domain that points to the old 2003 DC (CONPSRVF1-R2) - See attached image.
How do I fix this entry? Can I remove it or simply edit it and change it to my other DC (NPPDVMDC1-12)?
Thank you for your help.
