Ok, windows Xp machine. It is on a domain. There is only one LOCAL account, and it is disabled.
How I screwed it up:
I went into computer management , clicked GROUPS, and then double clicked Administrators. I was making sure no one else had admin rights to my PC, and I must have ACCIDENTALY removed myself while in the process. I USED to be part of the local administrators group (so that I could have administrative access to my local PC). However, I removed myself and now cannot do ANYTHING on the machine. I need to have local admin rights to this PC. How do I do this? I am positive no one did this to me on purpose, because no one was part of the local admin group, but me!
