Hi,
I have a network of 4 sites linked with e-line (ethernet) with cisco routers on every site. When the pcs from the remote sites try to connect on the DC (2003) on the central site they get the error that domain is not available…and will log you on with your roaming etc. We can ping, tracert, dns, domain everything is ok. VoIP works fine. You can also remove the pc from the domain but you can not join the domain from the sites as we get the error that domain is not available.
We tried everything but its always a dead end. No firewalls or filters are installed anywhere on the sites.
Any suggestions……???
