helping friend with computer has no admin rights. no user accounts in safe mode can get login after ctrl-alt delete but still a guest account. unable to load any programs or change bios to load disc for re install. asks for what appears to be domain login and shows mshome workgroup. this is an hp desktop with xp pro she used to have rights but can no longer access programs or do much of anything but surf the internet. dont know if this might be due to virus or what. her account says administrator but still guest account.
