[Samba] xp machines and samab 2.2.8a problem

[Linda Normann]

I am running Samba 2.2.8a on solaris 5.7 machines.
I have had 2 subnet working just fine for years.
I'm trying to add a 3rd subnet.
I am having a problem with my XP machines on a third subnet.

I have changed the registry so:
requiresignorseal = 0
and
requiresecurechannel = 0
and rebooted.

and

Enable NetBIOS over TCPIP is set.

I have two XP machines one with NETBEUI install and one without NETBEUI
installed
the one with NETBEUI installed can onyt see machines with NETBEUI install in
the network places (no samba servers)
and the XP machine without NETBEUI installed gets the following error when
trying to enter the domain:

"Mydomain is not accessiable. You might not have permission to use this
netowkr resource. Contact the administrator of
this server to find out if you have permissions.

The account is not authorized to log in from this station."


There is a 2000 machine running just fine on this subnet.


SAMBA SERVERS:

1st Machine):   SOL001

here's the smb.conf of the domain master browse (wins server) -
192.9.200.252

[global]
        log file = /tmp/samba/log
        lock directory = /tmp/samba
        workgroup = MYDOMAIN
        local master = yes
        domain master = yes
        preferred master = yes
        os level = 75
        wins support = yes
        security = USER
[homes]
        browseable = no
        writable = yes
[tmp]
        path = /usr/local/tmp
        writable = yes
        read only = no


2nd Machine):   SOL002

Here is the smb.conf of the subnet machine - 192.9.220.103
(This samba server is working fine)

[global]
        log file = /tmp/samba/log
        lock directory = /tmp/samba/lock
        workgroup = MYDOMAIN
        local master = yes
        domain master = no
        preferred master = yes
        wins server = 192.9.200.252
        os level = 50
        security = USER
[homes]
        browseable = yes
        writeable = yes
        read only = no
[tmp3]
        path = /usr/local/tmp3
        writable = yes
        read only = no

3rd Machine):   SOL003

Here's the smb.con of the new subnet machine - 192.9.206.12
(this is the samba server I am having problems with the XP machines)

[global]
        log file = /tmp/samba/log
        lock directory = /tmp/samba/lock
        workgroup = MYDOMAIN
        local master = yes
        domain master = no
        preferred master = yes
        wins server = 192.9.200.252
        os level = 65
        security = USER
[homes]
        browseable = yes
        writeable = yes
        read only = no
[tmp]
        path = /usr/local/tmp
        writable = yes
        read only = no
