[Samba] Samba turning

[Gardiner Leverett]

I have a two networks (across the country from each other) that are
connected
via ipsec through a Cicso pix.  There is samba running on a Linux machine
in the main office (call it office A) and users at the other office (B) need

to get to it.  After about three levels down, the response time back from
the server is very slow (as it appears to be caching the directory listing).

After as much as 60 seconds, the directory list appears. Going down further
sometimes causes another delay, but not all the time. Going back up the
tree may cause a delay as well.  Of the items I've been finding on line, 
the problem is probably the tuning of the server in office A.  Local 
users in office A see no problems.  The version I'm using is 3.0.21b-1
on RedHat 9.   

Here is the smb.conf (global part) for that server (I have adding items to 
the socket options list).  I have been experimenting with making this a 
pdc, but I haven't implemented it yet.  If anyone has some suggestions 
on how to fix this, I'd appreciate it.
