DEC FDDI Adapters Fail to Respond to Broadcasts

 Last reviewed: September 7, 1996
Article ID: Q150305
The information in this article applies to:
  • Microsoft Windows NT Workstation version 3.51
  • Microsoft Windows NT Server version 3.51

SYMPTOMS

When you use the Windows NT 3.51 DEFEA.SYS or DEFPA.SYS for the DEC EISA or PCI FDDI network adapters, the driver fails to respond to broadcast packets.

CAUSE

This problem occurs when the DEC FDDI adapter is reset. The problem occurs after a reset because the driver fails to register the broadcast address filter with the adapter after the reset.

MORE INFORMATION

When the DEC FDDI adapter is initialized the device driver is responsible for registering the broadcast address on the adapter. In event the device driver has to reset the adapter for any reason, it is the drivers responsibility to completely reinitialize the adapter, including registering the broadcast address filter.

The DEC FDDI adapter can be reset by the driver for a variety of reasons during normal use including requests to reset from a transport, and network conditions that generate adapter errors.

RESOLUTION

To correct this problem, apply the fix mentioned below.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 3.51. This problem was corrected in the latest Windows NT 3.51 U.S. Service Pack. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
