Now i want to join my xp to workgroup and when i do that it ask me for username and passowrd and then it says specified module does not exist

Usually you can just click OK on that dialog without specifying credentials.

You need credentials to remove the computer account from the domain. But you don't need domain credentials to switch the computer from domain to workgroup. Removing the computer account from the domain is optional.

  • i tried that but it again says specified module can not be found

  • Try it when you are disconnected from the network. I just verified that this does work by switching a Windows XP Pro computer from domain to workgroup, and I clicked OK without specifying credentials.

  • Doesn't sound familiar. It may be another issue, like some kind of system or network component that is not installed or registered correctly.

In my experience you have to enter the credentials of the Domain you are leaving.

  • You don't have to enter credentials. It will work without it.

Try the following:

  1. If your not using it, switch to the "classic" style login screen by doing ctrl+alt+del+del (yes, hit the del key twice).
  2. There should be a drop down on the login dialog box that allows you to choose between logging in to the domain or the computer itself (called "this computer" I think). Choose "this computer".
  3. Login using the computers administrator account and password.
  4. Right click on My Computer, choose Properties.
  5. Choose the Computer Name tab.
  6. Click the "Change..." button
  7. In the Member of section, choose Workgroup and enter the workgroup name.

I've never tried this with the domain controller offline, so I can't guarantee it will work.

  • Actually i am trying that because as DC is offline so i have to log in via local admin account but it ask for ceredentials

If the DC is offline how and which domain are you trying to Join??? If you want to unjoin, you could use David's technique. Press CTRL+ALT+DEL twice at login screen and login to the workstation locally with an administrator account, dont login to domain. Then you take properties of My Computer, go to Network tab and make your workstation member of a workgroup.

Let me know how it works for you... Another way is, issue this command

C:>netsh interface ip reset reset.log Your TCP/IP stack will be reset, all errors gone all memberships gone.

  • i want to unjoin not join

From the command prompt:

wmic computersystem where name!=null call unjoindomainorworkgroup

You might or might not need credentials, per the conversation above. WMIC is one hell of a tool, use it.


If all else fails you might try using sysprep. You'll need your Windows license key.

I've not done a machine with populated local accounts and I don't know what will happen to those local profiles.
