I configure something wrong in windows XP through gpedit.msc and restart the computer after that 80% of services of windows are stopped I tried manually to start that services but group dependencies services error 1068 comes. Then I saw that RPC service is also stopped then I try to start it but u could not start RPC service on local computer access denied error 5 comes. I am not even go to the properties of services to check that what's the prob. Now Lan, Audio, taskbar and lots of other things r not working. Plz look into this matter ASAP.
