A. XP and Win2K use DNS instead of NetBIOS to name domains. As a result, if you've installed only TCP/IP on the XP or Win2K client and you've disabled NetBIOS over TCP/IP, the client can't join an NT 4.0 domain. To enable NetBIOS over TCP/IP, perform the following steps:
- From the Start menu, select Settings, and click Network and Dial-up Connection.
- Right-click Local Area Connection, and select Properties from the context menu.
- Click Internet Protocol (TCP/IP), and click Properties.
- Click Advanced, and select the WINS tab.
- Click "Enable NetBIOS over TCP/IP."
- Click OK, and ignore the WINS error.
- Click OK to close all dialog boxes.
If you don't want to use NetBIOS over TCP/IP, you can instead use NetBEUI on all clients.
