Windows XP and Vista both use a default workgroup name of WORKGROUP. If you havent made any changes to the workgroup name on the Windows computers connected to your network then youre ready to go, because the Mac also creates a default workgroup name of WORKGROUP for connecting to Windows machines.
If you have changed your Windows workgroup name, as my wife and I have done with our home office network, then youll need to change the workgroup name on your Macs to match.
Change the Workgroup Name on Your Mac (Leopard OS X 10.5.x)
- Launch System Preferences by clicking its icon in the Dock.
- Click the Network icon in the System Preferences window.
- Select Edit Locations from the Location dropdown menu.
- Create a copy of your current active location.
- Select your active location from the list in the Location sheet. The active location is usually called Automatic, and may be the only entry in the sheet.
- Click the sprocket button and select Duplicate Location from the pop-up menu.
- Type in a new name for the duplicate location or use the default name, which is Automatic Copy.

After you click the Apply button, your network connection will be dropped. After a few moments, your network connection will be re-established, with the new workgroup name you created.
