Old computer name showing in group membership

Tutorials Win: Microsoft Windows Forum

I recently renamed a server, lets just say from ServerA to ServerB.
This server was a member of some local groups on another comptuer,
lets call this WorkstationA. It was also a member of some groups in
AD. Now all the groups in AD currently show the server with the new
name "ServerB". Howerver the local group membership on WorkstationA
still shows "ServerA". When I try to remove "ServerA" it lets me
delete it just fine, I click Add, type in "ServerB" and it finds it
ok, I then see it in the list. But as soon as I click Apply, it
changes the name back to "ServerA"

Does anyone know why this is happening and how to fix it? DNS shows
everything is correct, group membership in AD is all correct. It's
only this one workstation which keeps showing the old computer name.

Thanks

A quick guess is that when you renamed the server you changed its Common
Name from "ServerA" to "ServerB", but left the sAMAcountName as "ServerA$"
so the NetBIOS name of the machine is still "ServerA". The local SAM account
database used for local accounts is blind to Common Names (the value of the
cn attribute) and uses NetBIOS names. When you browse for the computer, the
object with cn=ServerB is found by the GUI, but the membership can only be
saved in the local group as ServerA, the NetBIOS name, or actually, <NetBIOS
name of domain>\<NetBIOS name of computer>.

If this is correct, change the sAMAccountName attribute of the server to
"ServerB$".

Thats what I thought at first as well, unfortunetly that wasn't it.
It turns out it just needed more time to update I guess. I let it sit
a couple days and I came back and it was fixed, the new name was
displayed. Go figure.
