Here's some strange news... Did an install of XP Home (Streamed SP2) on a normal system. when the first logon prompt was displayed with the default "Administrator" field already filled in for "user name", Instead of logging in with that I just changed Administrator to "Owner" and pressed enter. Ok so far no problems, logged in just fine with "Owner" account. Now, while in the owner account I created another admin account (peon) and logged in as peon, then deleted "owner" thru the standard "user accounts" option in control panel. THEN, while under peon, I used that command-line tool (renuser.exe) to raname the default "Administrator" account to "sammy" It worked the account was apparently renamed... BUT, then when I logged off of the peon account and tried to log into the default admin account (now sammy) it gave me an error of "could not login due to a logon restriction". WTF could that be? Hmmmmmmmmmmmmm...
