Can't Get Zone Information with Compaq Netflex II TR NIC

ID: Q123965

The information in this article applies to:

Microsoft Windows NT Server version 3.5

SYMPTOMS

When using the Compaq Netflex II Token Ring (TR) network interface card (NIC) on a Windows NT 3.5 server, you are not able to get zone information. Macintosh clients cannot see Windows NT 3.5 servers that use this NIC from Chooser. You cannot get zone information either when you are first configuring zones during the installation of Services for Macintosh, or later, after restarting the server or Services for Macintosh.

CAUSE

This problem is caused by the way functional addresses (TR equivalent of a multicast address) are added. There is no problem if the driver is written so it completes calls synchronously. However, if a driver is written so calls are made asynchronously, the request buffer becomes corrupted and no routing information is passed.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 3.5. This problem was corrected in the latest U.S. Service Pack for Windows NT version 3.5. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
