It's probably easy, but I've never seen it before.
My actual computer is called WXP-ACHAUDHARY (and this is also true in DNS). In AD, the title of the account is ACER-ABACUS001, yet properties shows that it knows the computer name is actually WXP-ACHAUDHARY. See my pic attached.
How can I correct the AD a/c name without disjoining the machine from the domain?
This is a single-domain 2003 environment with a WinXP client. ACER-ABACUS001 used to be the name of the machine, which was recently changed to WXP-ACHAUDHARY via newsid.exe and joined to the domain. Somewhere along the line AD seems to have gotten confused.
