    Based on the "multiple (2) responses" message, and the fact that you
    have occassional browsing problems, it sounds to me like you have
    competing domain masters. Check your Windows XP systems to see if any
    of them are configured as a PDC. Per the smb.conf manpage...

    " os level (G)
    This integer value controls what level Samba advertises itself as for
    browse elections. The value of this parameter determines whether nmbd(8)
    has a chance of becoming a local master browser for the WORKGROUP in
    the local broadcast area.

    Note :By default, Samba will win a local master browsing election over
    all Microsoft operating systems except a Windows NT 4.0/2000 Domain
    Controller. This means that a misconfigured Samba host can
    effectively isolate a subnet for browsing purposes. See
    BROWSING.txt in the Samba docs/ directory for details."

    If you still have problems, I'd suggest performing some payload dumps on
    your traffic. Unfortunately, it will take some advanced SMB experience
    to understand what you're seeing, so you might be better off just
    "tweaking <stuff>". ;-)
