Does anyone know of the following error I am getting when trying to add an additional DC to a domain. it’s a 2003 server adding to additional 2000 servers.
The operation failed because:
This active directory installation requires domain configuration changes, but whehter these changes have been made on the domain controller ***** is undetermined. The installation process has quit
The specified server cannot perform the requested operation
I have run adprep /forestprep and domainprep and left it a few hours for replication to occur between sites. This installation has to run over 2 separate wan links (and also 3 firewalls). 1 to the dc’s that are dns servers and 1 to the infrastructure master.
I think I’ve the ports open but not fully sure, would anyone know the required ports? Or have any advice??
