printing

Thanks Joel,
TCP Dump, showed that the server as querying a defunct DNS ip, when the
machine was taken off the DHCP and manually configured, it is behaving, and
doing it reasonably fast as well.
Why would the DNS affect the samba ? Doesn't it use WINS for everything to
locate machines ?
Now though I am getting a constant stream of the same error to the machine
specific logs, again smb and nmbd logs are showing up nothing, error is as
follows:
[2002/09/03 11:08:15, 0]
libsmb/cliconnect.c:attempt_netbios_session_request(1091)
attempt_netbios_session_request: PC194-70 rejected the session for name
*SMBSERVER with error Not listening on called name
[2002/09/03 11:08:15, 0]
rpc_client/cli_spoolss_notify.c:spoolss_connect_to_client(98)
connect_to_client: machine PC194-70 rejected the NetBIOS session request.
Machine 194-70 is my WinXP machine, why would the samba server be trying to
establish a netbios session to it ?
I have enabled Netbios over TCP for my WinXP machine, and it has the WINS
server entered in the WINS field.
The wins.dat on the samba WINS server (not the problem machine), contains
this line for pc194-70:
"PC194-70#00" 1031316178 128.250.194.70 64R
And no others.
Any clues as to what it causing the extraneous vomit in my logs ?
