Waiting For Group Policy Client-Terminal Services session environment crashes on TSVIPSrv.dll, no Citrix updates involved

On a Windows 2008 R2 workgroup server, no domain involved, get this error every few days, no one can log in to Remote Desktop, get the Waiting For Group Policy Client error, there are NO custom Group Policies either:

Faulting application name: svchost.exe_SessionEnv, version: 6.1.7600.16385, time stamp: 0x4a5bc3c1
Faulting module name: TSVIPSrv.dll, version: 6.1.7601.17514, time stamp: 0x4ce7ca09

Anyone know of a fix?

Thanks in advance!
