After a Windows XP Media Center Edition 2004-based computer that is joined to a domain is upgraded to Windows Vista Home Premium, the computer remains joined to the domain

Consider the following scenario:

• You join a Microsoft Windows XP Media Center Edition 2004-based computer to a domain.
• You upgrade the computer to Windows Vista Home Premium.

In this scenario, you experience the following problems:

• The Windows Vista Home Premium-based computer remains joined to the domain even though you cannot join a Windows Vista Home Premium-based computer to a domain.
• The Parental Control feature is disabled on the Windows Vista Home Premium-based computer.

To resolve this problem, change the computer so that it is a member of a workgroup. This change will disjoin the Windows Vista Home Premium-based computer from the domain. To do this, follow these steps.

Note We recommend that you have a local administrator user account and a password that you can use to log on to the computer. Then, you can change the computer so that it is a member of a workgroup.
