Scripting

If the machine is already in the domain and the new name is already in the domain this will occur.  Do not precreate the new name when renaming a machine already in the domain.  the only other thing is to create a script that remove the machine, rename the machine and rejoin it to the domain.  Since you are using the k2000 you want to rename the machine before you join it

This is a script to rename a machine in the domain to a existing name in the domain

start /wait Wmic computersystem where name="%computername%" call unjoindomainorworkgroup

start /wait wmic.exe  computersystem where "caption='%computername%'" rename newname

start /wait cscript.exe -b c:\windows\w2d\join_domain.vbs tmccacad.tmcc.edu domainuser password domainserverIP

shutdown -r -t 1

join_domain.vbs file:

Const JOIN_DOMAIN             = 1
Const ACCT_CREATE             = 2
Const ACCT_DELETE             = 4
Const WIN9X_UPGRADE           = 16
Const DOMAIN_JOIN_IF_JOINED   = 32
Const JOIN_UNSECURE           = 64
Const MACHINE_PASSWORD_PASSED = 128

If WScript.Arguments.Count < 3 or WScript.Arguments.Count > 4 Then
  WScript.Quit
Else
  strDomain   = WScript.Arguments.Item(0)
  strUser = WScript.Arguments.Item(1)
  strPassword = WScript.Arguments.Item(2)

'set DNS IP address
  If WScript.Arguments.Count = 4 Then
    strDNSIP = WScript.Arguments.Item(3)
    Set objShell = CreateObject("WScript.shell")
    objShell.Run "netsh int ip set dns  ""local area connection"" static "& _
                  strDNSIP &" primary",0,0
  End If

End If


Set objNetwork = CreateObject("WScript.Network")
strComputer = objNetwork.ComputerName

Set objComputer = GetObject("winmgmts:{impersonationLevel=Impersonate}!\\" & _
                             strComputer & _

Hi and thx for the script! Problem is I want a specific computer name. I want to use the serial number from the computer, like this : DT-83ur4jkj or LT-03ir0if. Thats why I use wsname.
