Samba problem with a WinXP Home box

I have a problem with a WinXP Home machine using Samba on a small home
network. Here are the details:

-Samba 3.0.10
-3 machines: VectorLinux v5 (smbserver), VectorLinux v5/Win98SE dual boot
(wolf), WinXP Home (andrea), through a router. -workgroup is "HOME"
-smb.conf is:
[global]
encrypt passwords = yes
guest account = smbguest
netbios name = MYSMBSERVER
security = share
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
IPTOS_LOWDELAY wins support = yes
workgroup = HOME
[pub]
path = /cifs/pub
read only = no
guest ok = yes
guest only = yes


The problem is that the other 2 machines (smbserver and wolf) can see the
WinXP Home machine (andrea) in a browsing window but cannot connect to it
nor see its shared folders. "andrea" does not have a firewall. All
machines happily ping back and forth. Here is a LinNeighborhood log while
attempting to see "andrea" shares from "smbserver":

GetSMBShare:smbclient -L ANDREA -U% -W HOME -d3

Sharename Type Comment
--------- ---- -------
Error returning browse list: NT_STATUS_ACCESS_DENIED

Server Comment
--------- -------
ANDREA Andrea's Computer
MYSMBSERVER Samba 3.0.10

Workgroup Master
--------- -------
HOME ANDREA

An attempt to connect from the Win98SE machine "wolf" produces a Network
Neighborhood window box stating: "\\Andrea is not accessible. No
permission to access resources". Attempts to connect from Konqueror (using
smb://) pops up an "Authorization Dialog" window "Please enter
authentication information for Andrea". If I enter a valid WinXP login
name and password it still gives the same error.

I suspect something is wrong with the WinXP Home machine setup, but I have
been over it numerous times, to no avail. All seems well (Microsoft Client
settings, TCP/IP settings, WINS server setting, LMHOSTS).

I am considering removing all network settings and TCP/IP and Microsoft
Client protocols and starting from scratch to reset all of "andrea"
network on that machine. Any other ideas or WinXP Home command line
facilities I can use to repair it will be much appreciated.
