I upgraded my server from nw6.5sp4 to sp6 last night, and printing has been down since. I've tried moving it to another server, I even deleted and recreated the broker, manager and printer agents. Now I'm getting the following error on the server: (no, that's not a typo, that's what it says.)

Failded getting host name, Error -1

Any idea what host name? Where could I configure it? The manager loads and shows the printer agent as idle, but print jobs don't go through. They don't get hung up as far as I can tell, they just disappear. HELP!
