DC replication broken
Posted on 2016-09-19
I have a network with a few DC. One of them is SBS 2007. That server is no longer running Exchange but it is used for Document redirection and more importantly RD Gateway services.
This was a physical server that recently was converted to a VM.
All of a sudden I am having very strange issues. I believe the problem is all related to replication. An OU is missing on SBS server. Even DNS is not quite working correctly. I can't access a member server by \\servername I get the error "The target account name is incorrect." I can ping servername and servername.domain.local What is very bizarre is any workstation that has SBS server as it's DNS server, also gets this message. I change the workstation DNS to point to another server and they can access the member server.
In HKLM\System\CurrentControlSet\Services\NTDS the key DSA not writable is set to 4. That appears to be from converting to VM
In sites and services when I try to replicate from that server I get "The naming context is in the process of being removed or is not replicated from the specified server"
I ran repadmin /showutdvec servername dc=lf,dc=local.
It shows the SBS server as "Retired" and it also shows it it replicating. I believe this is the way it should be since I converted it to VM.
Is there a way to fix this. Is demoting the SBS server the only option?
