Bruce,
Novell client opens port 427 TCP. My services file reports this port to be known as 'svrloc'. You can bluescreen Win95/98 with Novell Client versions 3.0 and 3.0.1 by sending a SYN to this port, as you would with 'nmap -sS -p 427 <target>'. This is quite fatal. The only recovery seems to be a power reset.
Novell always recommends using the latest client versions, which is now Novell Client v3.1 for Windows 95/98, plus Client Service Pack 2. See the full TID here: Required Novell Client versions (Last modified: 4 OCT 1999) http://support.novell.com/cgi-bin/search/tidfinder.cgi?2945422 Professional network administrators use the ZENworks product to upgrade all clients to the latest version level at once. ZENworks Starter Pack and the clients can be downloaded for free, so it can be done quite easily, without purchasing any additional software or visiting every workstation for manual updates. I suggest you find a way to test the reported issue with the latest client, and blame Novell only if it is still there.
