samba - Feb 2004 - Windows 2000 & Samba

I'm pulling my hair out over this.  I replaced an NT4 box with a Red Hat
8 box running samba-2.2.7-5.8.0.  I've got various Windows boxes
throughout the district.  I've got a 2000 Adv. Server box that can see
the samba share fine.  I'm not trying to get a new Dell box running 2000
Pro to see it.  Nothing.  I first tried with only TCP/IP, then added
NetBEUI, but the same.  I run "net view \\server", and I get a
"System
error 53 has occurred.  The network path was not found".  For the heck
of it, here's my smb.conf:
# Samba config file created using SWAT
# from 0.0.0.0 (0.0.0.0)
# Date: 2003/03/31 13:54:59

# Global parameters
[global]
        log file = /var/log/samba/%m.log
        passwd chat = *New*password* %n\n *Retype*new*password* %n\n
*passwd:*all*authentication*tokens*updated*successfully*
        socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
        obey pam restrictions = Yes
        create mask = 0777
        username map = /etc/samba/user.map
        encrypt passwords = yes
        passwd program = /usr/bin/passwd %u
        wins support = Yes
        dns proxy = No
        netbios name = SERVER
        writeable = yes
        printing = lprng
        server string = District Office PDC
        unix password sync = yes
        workgroup = OFFICE
        directory mask = 0777
        max log size = 0
        pam password change = Yes

[homes]
        comment = Home Directories
        valid users = %S
        read only = No
        create mask = 0664
        directory mask = 0775
        browseable = No

[printers]
        comment = All Printers
        path = /var/spool/samba
        printable = Yes
        browseable = No

[data]
        path = /home/data
        read only = No
        delete readonly = Yes

I'm open to anything here.  All the 98 machines work fine, and the 2000
Adv. Server box works fine.  It's just this new 2000 Pro box that's not
cooperating.

Thanks!
