Unable to DEMOTE a Windows 2000 Domain Controller.
I have WIN 2000 DC and I added a new WIN 2003 DC
All FSMO Roles are transfered to WIN 2003 and it is the Global Catalog as well.
Both Servers have AD integrated DNS.
The problem is, I am not able to DEMOTE my WIN 2000 DC , While doing DCPROMO, It is not able to connect the WIN 2003 DC with FQDN . It keeps asking me Enterprise Admin's Username and Password, even though I am already an enterprise admin.
Then I tried to access the 2003 DC with NETBIOS name, No problem, I can see all the SHARED folders.
Even with IP Address, I can connect to the WIN 2003 DC
The only thing is, I am not able to connect using FQDN . Because of this, Replication ( FRS Service ) also failing.
I checked the DNS entries and it is perfect and I even added an entry in HOSTS file for the 2003 DC.
Is there anything else I should check?
This is something weird . NETBIOS HELPER SERVICE is running in both SERVERS ( Well, I did a lot of google search and tried almost everything , but no luck )
Any help much appreciated.
