I had recently joined my Win7RC1 Desktop to a domain example.HQ.com and everything works except for disk defrag, I get the following error message....This program is blocked by group policy, for more information contact Systems Administrator. I had reset local policy settings on my machine to default and enabled it in Group Policy. Any help would be nice.JohnWL

click on ur start button....then type run and in the run dialog box type CMD..then as administrator type gpedit.msc then it will ask for admin access and u can click continue then click on windows settings,then u double click on Windows Settings,then click on software restriction policies some options will display again then u click on security Level...then u will see Disallowed, Basic User and Unrestricted....right click on the first and check if is set to defaulf and change to right click on Basic User and set basic user as ur default security..............thanks u'r welcome and to encourage me pls state if it works for you or not
