Well I have a 2003 Server (Enterprise Edition) installed and promoted it to be a Domain Controller. The Computer name is r01msedc and netbios name is SSMSE. I have two machines, both of which are in the domain SSDMSE. One is BATTLE and the other is CASTLE. I am using Castle as the the License Server. So on the Castle machine, I log in as the Administrator and Log on to as SSDMSE, since I chose the option of Enterprise instead of your domain or workgroup.I activated the License Server and installed CAL's from Microsoft. and log off the machine. Than I log on to the Battle, and go into Licensing Manager, it does not find any license servers at all. So I go back into Castle ( Administrator , Castle ( Local Computer ), go into license Manager it does not find any license servers. If I log off and log back on to ssdmse domain in the castle machine it finds the license server. I hope I made sense. I have also added the DefaultLicenseServer key in the registry as well. Does anyone know a fix or ideas I would really apreciate it. Thanks
