[Samba] explorer.exe crashing at login

[Orion Poplawski]

We're running a network of Windows 2000 SP3 machines with Samba 2.2.7 as 
the PDC and roaming profile store.  Certain users logging onto certain 
machines will see an error dialogue pop-up saying explorer.exe has 
generated errors and will exit.  This keeps popping up and to only 
course of action is to ctrl-alt-del and logout.  For most people, 
everything works fine.

I've been able to clear it up temporarily my moving the profile 
directory out of the way on the server, but the problem can re-occur.

smb.conf:
[global]
    username map = /etc/samba/smbusers
;   nt acl support = no

;Run as a PDC
    domain logons = yes
    security = user
    os level = 99

    encrypt passwords = yes
    smb passwd file = /etc/samba/smbpasswd
    socket options = TCP_NODELAY
    local master = yes
    domain master = yes
    preferred master = yes

    logon script = %U.bat
    logon path = \\%N\%U\profile
    logon drive = H:
    logon home = \\%N\%U
    wins support = yes
    domain admin group = @wheel
    share modes = no

[netlogon]
         comment = Net logon scripts
         path = /var/netlogon
         create mode = 0600
         directory mode = 0700
         writable = no
         guest ok = no
         browsable = no


This seems to have started after I made some changes to our samba 
server, and may have lost certain machine trust information, but I'm not 
sure.

Any help would be greatly appreciated.
