Automatic Discovery Method doesnt work

Hello,

We have moved our Ghost  Cast Server on a new Windows Server 2008 VM.

The client cannot establish a connection with the server when we select the automatic discovery method. If we put the IP Address of the ghost server instead of Automatic everything is working properly.

I have disabled the windows firewall and the anti-virus as well and same problem.

This was running properly on the old servers ( Windows 2003 Physical ), the new server is on the same network / range than the old one.

Any suggestions ?

Thanks
