[Samba] Samba (+ NAV?) and bad printer names?

[Steve Snyder]

At 4:00 every morning the 2 WinXP machines on my network generate a slew 
of queries to bad printer names.  These names are variations on the name 
of a valid printer exported by Samba.  

Samba v3.0.10 is running on a RHEL4 system.  It exports several shared 
drives and a single printer.  The printer is named "lj4500", is managed by 
CUPS v1.1.22, and works correctly via Samba from both WinXP boxes.  

Here's a snippet of my smb.conf file:

   load printers = yes
   printing = cups
   printcap name = cups

So what is going on with those WinXP machines at 4:00AM?  The only thing I 
can think of is the daily system-wide scan done by Norton Antivirus (NAV).  

Can anyone shed some light on what is going on here and how I can stop 
these queries to bogus printer names?  

Thanks.
