Workstation Service Does Not Start

This article was previously published under Q197157
When you start or reboot a computer that has two network adaptersinstalled, the Workstation service may not start and the following errormessages may appear in Event Viewer:
   Event ID: 3870   Source: Workstation   Description: <computer name> is not a valid computer name.   Event ID: 7023   Source: Service Control Manager   Description: The Workstation service terminated with the following   error: A duplicate name exists on the network.				
This behavior can occur if both network adapters attempt to register thesame NetBIOS name with the Microsoft Windows Internet Naming Service(WINS).
To resolve this issue, disable the NetBEUI protocol that is bound to oneof the network adapters. To do this:

  1. Click Start, point to Settings, click Control Panel, and then double- click Network.
  2. Click the Bindings tab, and then click All Adapters in the Show Bindings For box.
  3. Click the plus sign next to the second network adapter.
  4. Click NetBEUI Protocol, and then click Disable.
  5. Click Close, and then restart the computer.
Microsoft has confirmed this to be a problem in the products listed above.
For more information about NetBIOS names and WINS, see the followingarticle in the Microsoft Knowledge Base.
