samba - Feb 2006 - Connecting to SAMBA for first time takes a very looong time

I'm running Samba 3.0.14a-2 on FC4 as a print server.  The system is 
joined to the domain and I'm using the domain security model.  Pretty 
much, it's configured like my old Samba 2.2.7 server (which this new box 
is replacing).  On the PC side, printers are assigned to a user via a 
VBScript running under a group policy.  The first time that script runs 
and tries to add the printer to the windows machine for a specific user 
(all our windows machine are XP SP2), it takes anywhere from 2 to 6 
minutes.  The next time that same user logs in, it's quick.  When a 
DIFFERENT user logs in for the first time to the SAME machine, it again 
can take from 2 to 6 minutes.  If, however, the same script is instead 
attempting to connect printers on the Samba 2.2.7 server, all is quick 
in every case.

I'm not sure if this is a configuration issue (don't know what parameter
might affect it), a bug, or a problem in the windows domain.  Any idea 
where to look and for what?  What information might be helpful for me to 
post.  I have included below the global, printers and print$ sections of 
smb.conf.
