[Samba] Print queue not viewable from Windows XP

[Zoran Ovcin]

I am using Samba PDC LDAP box as a file and print server on our local 
network.

The printer is loaded and I can print on it, using the usual way:

    printcap name = /etc/printcap
    load printers = yes

    printing = lprng

[printers]
    comment = All Printers
    path = /var/spool/samba
    browseable = no
    guest ok = no
    writable = no
#   public = yes
    printable = yes

I can print to this queue from an Windows XP Professional workstation, 
as well as from other systems (Windows 98,...), but I can not view the 
print queue from the XP.

I can view the queue from W98, remove a job, but, XP says when I try to 
Open the Printer, on its top bar:

lp on server Access denied, unable to connect

Does anybody else have the same problem? Can somebody help me solving it?

In my experiments I used the XP and the W98 computers as a workgroup 
members, but the same problem happens with a Windows 2000 Professional 
workstation as a Domain member.

Not forgetting to mention: defining of lpr, lpq and lprm in the smb.conf 
in the usual way did not help.
