I recently changed the IP addresses on two NetWare servers. One server is
running NW5.1, the other is running NW6. After the change, printing for
most people that connect to the NW6 server stopped working. Printing for
users connecting to the NW5.1 server was not affected at all. We run
queue based printing, not NDPS.

Ultimately, I had to login at the affected PCs (running XP) as NW
Administrator and printing started working again. I don't understatnd why
this happened. Any ideas? I like to know if I did something wrong.
