[Wylug-help] Samba authentication problem

LAN - mixed architecture - 2 x win98, 1 x winME, 1 x win2k, 3 x Mandrake Linux
10.0.  Most samba activity is between the Mdk boxes, file-moving, etc.

Versions - Mandrake 10.0, with all updates applied, Samba 3.0.6-4.1

I had a properly working lan, with occasional problems between box1 and box2
(Mdk boxes).  Now I have no connection between them, for file-sharing
purposes, at all.  Box3, another Mdk box, uses box1 as print server, and has
no problems in printing, but has the same problem as box2 for file sharing.
Ping is fine, both by name and number.

Scenario -
Box2 uses LinNeighborhood to attempt to connect to box1.
A mount appears in the lower window of LN.
It is not possible to browse that mount
The mount will not umount in LN or from the CLI
The only way to break the situation appears to be to reboot.
