Windows Server 2003 Terminal Services Manager you could not be authenticated on this server


I keep getting an error when I try to view the remote users for several servers in my domain. When I open terminal services manager, the servers are displayed, but when I double click on them to display the logged on users, in the pane to the right, I get an error that says "you could not be authenticated on this server". For generally about 5 minutes, I keep getting the same error, but if I leave TS Manager open, after about 5 minutes, I'm able to authenticate and see the server. This began happening out of the blue about a month or so ago. I use this regularily as we are in a complete RDP environment for all remote users. Having to wait 5 minutes is sometimes the difference between being able to fix a problem and not.
I've done some online research and found that it seems people are saying to make sure that the "remote registry service" is started on the target server. Remote registry service is started on all the servers with the specified issue. Does anyone have any other suggestions?
There have been no upgrades to the OS except for updates that have been applied by Windows Update.

What Antivirus/AntiSpyware/AntiHacker apps are you running? you may need to loosen the security settings to allow for remote admin.

I'm using Vipre Enterprise. It isn't any issue on the other servers...only on this cluster of 4.
I am afraid I don't have an answer, only suggestions.

There has to be something timing out between you and the Windows box, whether it be your LAN adapter, the Switch, any router between you and it, the Switch it's connected to or it's LAN adapter.

It could also be a software issue, LAN drivers or a plethora of Windows Issues that could delay an remote admin request.

Attempt to connect Check the Event Logs and if it when it fails check the Event Viewer (Start -> Program Files -> Administrative Tools -> Event Viewer)
Browse through the events right around the time you connected and see if anything broke, timed out etc... This may reveal a route to repair.

If that does not work make sure all Windows updates are applied on All affected machines, Make sure any Routers or Managed Switches have updated firmware, make sure the LAN drivers are up to date on all the machines.

This may all seem very basic but you have to start somewhere, I find that sometimes a very complicated problem can have a very simple answer, sometimes you have to take several steps back and start with the basics.

After you troubleshoot in this way it should at least give something more specific to go on. If you find something post back here, we can all benefit from a solved issue like this.

Clint--thank you for your comments and suggestions.

I do have a solution to report back. It turns out it was a time issue on the virtual servers. For some reason, the servers weren't synching their time with the DC. So, once I corrected the time to match the DC (and the current time), the authentication issue went away. Like you said, complicated issue, simple solution.
