Printing to a Samba Printer triggering a DNS lookup and dialling the modem

[Doug Gray]

Joel,

"Putting the linux server into an lmhost file might prevent DNS lookup up. "

That is the answer.

I had not dreated an LMHOSTS file on the WinME computer so the broadcasts were
tripping the dialer.

Thanks,  I also be giving the tcpdump a run to see its usefulness.

Regards,
Doug
