NDIS Driver Fails To Check Functional Address

• Microsoft Windows NT Workstation versions 3.5, 3.51, 4.0
• Microsoft Windows NT Server versions 3.5, 3.51, 4.0

SYMPTOMS

On a computer running Windows NT and using Token Ring network cards, packets that are addressed to certain functional addresses may be dropped, indicating a failure in the NDIS (network driver interface specification) driver.

CAUSE

The NDIS driver fails to check for combined functional addresses in order to find a matching address to the destination functional address of the incoming packet. A combined functional address is the logical OR of multiple functional addresses that the token ring network card listens to.

RESOLUTION

The NDIS driver has been modified to check for combined functional addresses.
