error 2: The system can not find the file specified.

This error may be intermittent, and is usually caused by a problem in the registry. If your system's Control Panel-> System -> Hardware -> Device Manager lists a network adapter that is not present in the system, this error can occur. You may not be able to remove the phantom adapter with normal tools in which case editing the registry is required.

You might be able to solve the problem by checking/changing the order of 'Adapters and Bindings' in Control Panel->Network Connections -> Advanced Menu item -> Advanced Settings: put (Remote Access Connections) at the top of the Connections list.

If this does not help, you will need to edit the registry. The phantom network adapter and all references to it need to be deleted. See the following Microsoft Knowledge Base Articles for more information:

• MS KB 169116
• MB KB 165846

If deleting the phantom adapter does not help (or you cannot find a phantom adapter), you may need to remove and reinstall remote access service (RAS), other installed network adapters, and all installed network protocols.
