[Samba] Remote Samba Servers Timming Out....

[Shane Drinkwater]

Hello,
I am have a strange problem with remote samba servers and I am hopping some
one can give me a insite into what is happening. First is the Setup I have 2
remote sites connected to a central site by 2 T1 Lines. The two remote sites
each have a IBM X305 Running RedHat 9 and Samba 3.0.2a per/Site. Each box
per site has been configured to be the local master(cross Subnet
Browsing).All Sites use  a class C Subnet. So 
Remote Site A --> 172.27.20.0/24 x305 RH9, Samba 3.0.2a
Remote Site B --> 172.27.10.0/24 x305 RH9, Samba 3.0.2a
Central Site --> 172.27.1.0/24 Has 1 Windows 2000 Server Box Running Wins(
172.27.1.17), 2 Domain Controllers win NT 4.0
( 1 Primary, 1 Backup) all servers are connected to the wins box for name
resolution.

Below is a example of the remote sites config.
#======================= Global Settings
=====================================
[global]
#================== remote Annouce Settings
==================================
        remote announce = 172.27.1.7
        remote browse sync = 172.27.1.7
#=============== Local Master Settings===========================
        domain master = no
        local master = yes
        preferred master = yes
        os level = 65
#===============================================================
        log file = /var/log/samba/%m.log
        load printers = yes
        smb passwd file = /etc/samba/smbpasswd
        passwd chat = *New*password* %n\n *Retype*new*password* %n\n
*passwd:*all*authentication*tokens*updated*successfully*
        obey pam restrictions = yes
        socket options = TCP_NODELAY SO_SNDBUF=8192 SO_RCVBUF=8192
        wins server = 172.27.1.17
        encrypt passwords = yes
        passwd program = /usr/bin/passwd %u
        dns proxy = no
        netbios name = athena
        server string = Samba Server
        printing = lprng
#       unix password sync = Yes
        workgroup = CSQ
        printcap name = /etc/printcap
        security = domain
        max log size = 0
        pam password change = yes
        large readwrite = yes
        veto files = /*.eml/*.nws/riched20.dll/
        write cache size = 128000

#======================Printer Stuff ====================================
        printer admin = @CSQ+"Programmers", at CSQ+"Domain Admins", at CSQ+"Domain
Users", at CSQ+"PA Doctors"
        lprm command = /usr/bin/lprm -P%p %j
        queueresume command = /usr/sbin/lpc -P%p start
        lpq command = /usr/bin/lpq -P%p
        lppause command = /usr/sbin/lpc -P%p stop
        print command = /usr/bin/lpr -r -P%p %s
        lpresume command = /usr/sbin/lpc -P%p start
#=======================Winbindd Stuff ==================================
        password server = *
        winbind uid = 10000-20000
        winbind gid = 10000-20000
        winbind separator = +
        template shell = /bin/bash
        template homedir = /home/%D/%U
        winbind cache time = 60
        winbind enum users = yes
        winbind enum groups = yes

After starting the servers everything seems to work for about 1 week. That
is Cross subnet Routing is working. I can double click on server and see
shares, printers, etc. But after that 1 week things stop working I can't
double click on the two remote servers. If I try to mount a resource from
the central site I get the following windows 2000 workstation error:

"System error 53 has occurred.
The network path was not found."
on a Windows 2000 Box. 

I also took a samba box on my central site and used smbclient -L athena
smbclient -L athena

So I know that the Box is alive and well. Why can't it comminicate with
windows clients at a differant location ??
