Backup Exec 2012 Not Populating Selection Lists

Hi,

We are attempting to migrate to BE2012 and have the software installed on a server 2008r2 system, the software is licensed, when i try to view selection lists of servers, even the local host the system just attempts to load then comes back with nothing.

In my example i have attempted to expand the local server and servers on other subnets, the agent is able to be pushed to these machines and the account that i am using has Dom Ad rights.

Are there any suggestions as to why this might be happening?

Thank You
