I added the casuser to the administrators group and that has done the trick.

Vinod AryaMaking casuser an administrator has done the trick.  The odd thing here is that this server was build back in July and it just suddenly stopped working.  Maybe someone had thought that casuser shouldnt be in that group and kicked it.Thank ...

It is windows 2008, do you want the event logs? They dont seem to have any errors.

The page file is 8192 which is double my ram.  Still get the same issue.  Changed Casuser to a different password with no changes seen.

I tried this but I am still not able to get the Cisco prime Daemon manager to start.
