How to Change the Workgroup Name in Vista

information   Information
When you first set up Vista or connect to a network, Vista automatically creates a workgroup and gives it a default name of WORKGROUP. Computers in a workgroup network must all have the same workgroup name in order to join that workgroup. This will show you how to change your computer workgroup name so you can create or join a workgroup.
Note   Note
In a workgroup all computers are peers; no computer has control over another computer. Each computer has their own user accounts, so you cannot use another computer in the workgroup unless you have a user account setup on that computer.
warning   Warning
If you change the name of an existing workgroup, a new workgroup will be created with that name instead. If your computer was a member of a domain before you joined the workgroup, it will be removed from the domain and your computer account on that domain will be disabled. Computers on a workgroup must have a unique computer name so they can identify and communicate with each other.
