Remove-Computer

Updated: April 21, 2010

Applies To: Windows PowerShell 2.0

Removes the local computer from its domain.

Syntax

Remove-Computer [[-Credential] <PSCredential>] [-Force] [-PassThru] [-Confirm] [-WhatIf] [<CommonParameters>]

Description

The Remove-Computer cmdlet removes the local computer from its current domain.

When you remove a computer from a domain, Remove-Computer also disables the computer's domain account. When the computer is in a domain, you must provide credentials, even when they are the credentials of the current user, and you must restart the computer to make the change effective.

To get the results of the command, use the Verbose and PassThru parameters. To suppress the user prompt, use the Force parameter.

Parameters

-Credential <PSCredential>

Specifies a user account that has permission to perform this action. The default is the current user.

Type a user name, such as "User01" or "Domain01\User01", or enter a PSCredential object, such as one generated by the Get-Credential cmdlet. If you type a user name, you will be prompted for a password.

To remove a computer from a domain, you must use the Credential parameter, even when you are using the credentials of the current user.

Notes

This cmdlet will not remove a computer from a workgroup.

Although the cmdlet does not require the Credential parameter, commands to remove a computer from a domain fail if it is omitted.

Example 1

C:\PS>remove-computer -credential domain01\admin01 -passthru -verbose; restart-computer

Description
-----------
These commands remove the local computer from the domain to which it is joined.

The first command removes the computer from the domain. The command uses the Credential parameter to supply the credentials of a domain administrator. It uses the PassThru parameter and the Verbose common parameter to display information about the success or failure of the command.

The second command uses the Restart-Computer cmdlet to restart the computer, which is required to complete the remove operation.

The semi-colon (;) separates the two commands.







Example 2

C:\PS>remove-computer -credential domain01\admin01 -force; restart-computer

Description
-----------
This command removes the local computer from its domain without requiring user confirmation. The Force parameter suppresses the user prompt that appears by default.
