I was wondering whether anyone can confirm something. Im looking at disabling error reporting using a policy but it isn't applying. I have read all the information and now I think that system.adm is incorrect. System .adm from a 2003 SP1 / SP2 and a 64 bit SP2 servers gives an entry KEYNAME "Software\Policies\Microsoft\PCHealth\ErrorReporting" VALUENAME DoReport VALUEON NUMERIC 0 VALUEOFF NUMERIC 1 The Software\Policies\Microsoft\PCHealth\ErrorReporting is being updated but the values are being ignored. When I manually turn off error reporting the DoReport value is changed under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PCHealth\ErrorReporting Has anyone else come across this ?
