Problem: Only when viewing windows 7 system through RDP (i.e.by mstsc.exe ) quite often in 10 minutes the connection get disconnected. Observation: when we open the WMI service we get like this: another required service is not available. also the dependant service components are also empty. It give win32:RPC service is unavailable., where as the RPC (remote Procedure Call ) should be vissibale as dependant service. The same thing exist for the SMS AGENT HOST - service, which should show WMI as dependant, but shows empty. Simillarly for RDP service also. In any Service if we check the dependency TAB, we get "WIN32: Access is denied" Pls kindly suggest at the earliest, as we get the same for all WIN 7 systems (only).

Hi, It seems the permission of the WMI service is incorrect. Please open a command prompt with elevated privileges, type: SC SDSHOW WINMGMT The correct permission should be below. D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;IU)(A;;CCLCSWLOCRRC;;;SU)S:(AU;FA;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;WD) If the permission is incorrect, you can use SC SDSET to change the permission.
