How to change account type in XPP

Posted on 2011-10-15

  I have a workstation with XPP that is just disjoined successfully from Windows 2000 Server DC. When I restarte the computer, I logged in as local administrator, but quickly learned that I could not change RDP Port number. So I ran CompMgmt.msc and discovered that the local admin account "administrator" was not a member of "administrators" group. When I try to add administrator account to the member of the administrators group, I get an error message as seen below.
"one or more errors occurred while recording group membership changes for user administrator."
"the following error occured while attempting to save properties for user administrator: Access is denied."
  I tried to join this computer to the domain again, but I don't even have that option anymore - it is Domain Join Options are all greyed out. I figure that since I don't have admin previliage, I can't even do that.
  Is there anyway to create a new account as admin or change existing administrator account group membership from Users to Administrators?

    You can reset any password. Pick one the is part of the administrators group

    I am not interested in recovering forgotten password.
    I know the passwords because I created them.
    However, for some reason, accounts have been become NON-Administrative accounts.

    Are you sure that you are actually logging in as the local admin? If you attempt to remove the local admin from the admin group, you will receive an error, so I'm not sure how you were able to get to this point to begin with.

    Even though I did not find the solutions to the problem, I just like to move. Probably I won't get much help on this subject.
