The information in this article applies to:

- Microsoft Windows NT Server versions 3.5, 3.51 
-------------------------------------------------------------------------------


SYMPTOMS
========

When AppleTalk Event ID: 46 errors start, Macintosh clients that are attempting
to communicate with the server stop responding. The NT machine will report:

  Event ID: 46
  description: Unable to allocate resources from the NDIS Wrapper.

Once this error begins, more Macintosh clients will hang and they will eventually
hang the Windows NT Server.

CAUSE
=====

In SFMATALK.SYS, the packet descriptors are allocated ahead of time from the
NDIS Wrapper. With several hundred Macintosh clients accessing the server, it is
possible that Windows NT will not have a packet descriptor ready when one is
needed.


STATUS
======

Microsoft has confirmed this to be a problem in Windows NT 3.51. This problem
was corrected in the latest Windows NT 3.51 U.S. Service Pack. For information
