FM server11 admin console cannot establish a connection to the admin server
I have a FM 11 server installed on a win7 pc that serves both Mac an PC clients.Whenever i log onto the admin console either on the host or remotely after a short while(approx 30 secs)the message unable to establish a connection to the admin server comes up and logs me out of the console.
The server is clearly working ok as all clients are connecting fine and the backups etc are all working.
I have cleared the java cache and applied all updates to Java and FM server but it makes no differance.
Any help would be greatly appreciated.
