We have an Enterprise network and no one really uses the local admin accounts, I just happen to notice it and when I researched more machines that's when I realized it had done it throughout the network. Good news- We did figure it out (Thanx Spyderman2) as we obviously have numerous Domain Admins with rights to change GPO's. Someone (who didn't know how to do it CORRECTLY) changed the GPO in "Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> Accounts: Rename administrator account, and instead of correctly disabling the service (by UNchecking the box) they ENABLED it by checking, then put the WORD "Disabled", hence renaming all Administrator accounts to "Disabled". Thanks for the help and Oh so glad we got it figured out!
