Hey

I am keep on getting Class(es) not found: "Win32_PerfRawData_LocalSessionManager_TerminalServices" (code: PE235) with my WMI Terminal Services (2008+) sensors, every time the issue occurs i am verifying that this class is working correctly thru WMI via PowerShell, but the PRTG Probe issues errors like that. These usually go away after PRTG Probe/server restart or monitored host restart, but this forces me to reboot servers/services at least once/twice a week because PRTG reports issues with WMI, are there any final resolution to these problems which is not including reboots of services/servers? I have already went thru most of WMI troubleshooting/best practices guides in this KB but the issue is keep on occurring again and again.

Please assist me with that issue.

Thanks Marti

Could you forward us Probe Status files from the corresponding probe to support@paessler.com? Simply add [Stephan Linke] to the start of the subject and I'll grab the case :)
