no matter what i do i still get this

Are your computer and account name the same? For some reason, this can cause errors... Also, if you're running xp with sp3, there's security issues... You got to uninstall sp3, then install sql 2008 r2 :)

yes they are the same , also im useing Service pack 1

Change your computer name so that they don't conflict... Should work then.

ya uninstallign it again and gona reinstall with dif server name tyvm for the help i never had this problem till now with same name but maybe its cause i changed name after i installed lol

changeing the server name didnt work same error gona uninstall and change name of PC then try again
