Admin Console not seeing clients

Hi guys. I have ran into a problem with my endpoint suite. On the admin console it appears as though all of my clients are dissconnect. Last connect established was recorded quite some time ago. All of the clients are up to date and running the latest version. The Clients appear to be running fine. They can see the license file on the server and can update their engine and virus definitions just fine. Is this just a bug with my admin console? And is there a way to fix this? Any help is much appreciated.

Which Admin Console are you using? Small Office or Enterprise?

For both make sure all services are running on the server running the console. It is possible (especially with EAS) that the Console service fails but the mirror is working, although usually you would be unable to login to the console in this scenario.
