My servers have recently decided to crash whenever a Mac client (the old
MacIPX-ish one from Prosoft) tries to connect to a server with an NSS
volume. It never happens on servers with traditional volumes. The
abend.log shows NSS.NLM as the executing process when the crash occurs.
This is very disruptive, as all users are locked out once a Mac user attempts
to connect. The server must be rebooted -- even the NUMLOCK key doesn't

The only recent change was the installation of Zenworks 6.5.

What does Zenworks change in NSS to cause such a seemingly unrelated crash?
