FIX: NetBIOS Returns Wrong Adapter Type for NetBEUI

 * }

SYMPTOMS
When an application calls Adapter Status (NCBASTAT) on a LANA number that corresponds to the NetBEUI protocol, the adapter_type field of the ADAPTER_STATUS structure for an ethernet card is incorrectly set to 0xFF. This is interpreted to be a Token Ring card. If a LANA number is used that corresponds to any other protocol (for example, TCP/IP or IPX/SPX), the adapter_type is correctly reported as Ethernet.

STATUS
This problem was corrected in Microsoft Windows 2000.
