AcceptClient(): Refused connection

[Meije Oppenhuizen]

Somewhere while trying to add a winprinter I managed to screw up my
CUPS-setup.
I can no longer access the CUPS-server from within my network.
The CUPS-server is running on a box named 'ezra' and should be servicing the
local network.

'netcat -u -l -p 631 & PID=$! ; sleep 40 ; kill $PID'
on a client gives 
[1] 9418
Can't grab 0.0.0.0:631 with bind
[1]+  Exit 1                  netcat -u -l -p 631
bash: kill: (9418) - Unknown process
Turned up the debuglevel to debug on the cupsserver and get this message in
the errorlog, whenever I try to contact from the local network:

D [07/May/2005:08:59:24 +0200] AcceptClient(): Refused connection from from
basicsaint.localnet

Some pointers would really be appreciated. I'm starting to pull my hair out
here.

Could someone please point me in the right direction?
