Apple Macintosh Clients Cannot See Windows NT Server After Upgrading to SP4

ID: Q216878

The information in this article applies to:

Microsoft Windows NT Server versions 4.0, 4.0 SP4

SYMPTOMS

Apple Macintosh clients are unable to attach and view files on the Windows NT Services for Macintosh (SFM) volume. This problem only happens with some network interface cards (NICs) after Windows NT 4.0 is upgraded to Service Pack 4 (SP4). The Intel Ether Express 8/16 is one of the NICs that exhibits this problem. Reverting back to SP3 resolves the problem. And, if there is a Seed Router on the network, the Windows NT Server computer is able to resolve the media access control (MAC) address of the Apple client.

CAUSE

Modifications made to Ndis.sys after SP3 broke functionality in Windows NT Server 4.0, which ignored Apple Macintosh broadcasts.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information on obtaining the latest service pack, please go to:
