How to Delete a Domain From a Computer

By Ruri Ranbe

Windows 8 won't allow you to connect your computer to more than one domain at a time, nor will it allow you to connect your computer to a domain and a workgroup simultaneously. If your computer is joined to a domain already, but you want to connect to a different domain or to a workgroup, you must leave the domain to which your PC is assigned. Alternatively, if you're a business owner or administrator and you want to disjoin a computer from your institution's domain, you can do so through Active Directory Users and Computers.

Via the Control Panel

Step 1

Sign in to your computer as an administrator. Press "Windows-W" to open the Settings screen and then type "sys" into the search box.

Step 2

Select "System" from the results to open the System window in the Control Panel and then scroll down to the Computer Name, Domain and Workgroup Settings section.

Step 3

Click "Change Settings" to open the System Properties window and then click "Change" to view your domain membership.

Step 4

Select "Workgroup" from under "Member of" and then enter a name for the workgroup, or use the default name. Click "OK" to leave the domain.

Via Active Directory Users and Computers

Step 1

Log on to your domain controller as an administrator and then right-click an empty area on the Start screen.

Step 2

Select "All Apps" from the context menu and then choose "Active Directory Users and Computers" from Administrative Tools.

Step 3

Select "Computers" from the console tree and then right-click the appropriate computer in the details pane.

Step 4

Choose "Delete" from the context menu to remove the computer from the domain.

Tips & Warnings

  • To remove a computer in AD Users and Computers, you must be part of the Domain Admins group, the Enterprise Admins group, or the Account Operators group.
