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
