I'm runing window 7 professional and the computer was connected to a network which had a domain controller running windows server 2003. I've taken the computer out of the network but I'm not getting and error running diagnostics / trouble shooting when I have a network connection problem etc. I get the message the Diagnostic policy service is not running.
I've tried all the fixes suggested which includes changing the permissions on the DPS/Parameters in the registry. I've tried this as administrator but every time i try to apply the change I get a Widnows Security message saying "unable to save permission changes on parameters". I've not been able to find a away around this. Can anyone provide a solution please.
