If you have installed Services for Macintosh and have the AppleTalk protocol bound to an NE3200 compatible driver, your computer will stop responding (hang) or be extremely slow when you start up Windows NT Advanced Server.

The following entry is recorded in your error log:

   The description  for Event ID [46] in Source [AppleTalk] could not be
   found. It contains the following insertion string(s) \device\atalkDdp.

   The Data in words is:
   0000: 00000000 005C0001 00000000 C000002E
   0010: 000A03E4 C001000D 00000000 00000000
   0020: 00000000 00000000


One of the transports hangs during its loading sequence. The NE3200 decides that it needs to reset because it's on a quiet network and it thinks that the card is hung. The problem is that if a transport tries to open the adapter while the reset is in progress, the open will be pending but does not get restarted when the reset completes. This bug will not be exposed except on a network with very low traffic.


Microsoft has confirmed this to be a problem in Windows NT and Windows NT Advanced Server version 3.1. This problem was corrected in the latest U.S. Service Pack for Windows NT and Windows NT Advanced Server version 3.1.
