2008R2 Remote Desktop Services - Winlogon.exe keeps crashing


2008R2 SP1, 64GB RAM, 8CPU.  Running, session host, RDS gateway, remote app. Latest patches.

System becomes unresponsive to logins, users on the system have no issues and i have to power cycle the vm to get it to respond to logins again. I have not been able to determine why the process keeps crashing but it is happening every day.

Any ideas?

Maybe this will help. Perhaps the VM needs more resources.

    Lack of system resources (hard disk space, memory, CPU)
    Corrupted Windows registry
    Service that has failed to start
