we have both virtual serves and physical servers. Windows 2003 and 2008 R2. All of sudden about 75% of our servers no longer accept any RDP traffic. We have not found anything in the EventLogs either. But, each server is still up and running. For the vsphere machines we can access each from the vSphere Console. and for the physical machines we can log in from the console. But they will not allow or accept any RDP traffic.
What can cause this?
