The diagnostic policy service on a 2008 server will not start: error 5 access denied. net start dps: The Diagnostic Policy Service Service service could not be started: a system error has occurred, system error 5 has occurred. access is denied. the event log gives no information as to what access was denied (security), leading me to suspect it is a registry permission (Trusted installer does have full control of the DPS hive). When attempting to use Process Monitor to see what is being denied, I see only sucess, buffer overflow, and name not found. (name not found mostly under hklm\system\ccs\control]wdi\...) Suggestions as to how this may be troubleshot?
