[Samba] Disapearing Drives

[Ron Garcia-Vidal]

I have been having a problem with my Samba server for about a month now 
and need help.  I am having users mysteriously losing access to drives 
during the day.  The drive will un-map itself and any further attempt to 
access it through wither Windows Explorer or just typing the UNC in the 
"Run" window will result in a "Drive or path not accessible" error.  On 
the samba side, nothing shows up in the logs on subsequent connections, 
so I'm unsure how to diagnose what the problem is.  Attempts to access 
the share from another machine as the same user are successful.

The fix for this seems to be, either reboot the client (less preferable 
because the user gets upset) or restart the smbd on the server.  Either 
way, subsequent share access is restored.  Unfortunately, this problem 
is reoccurring several times a day and I find myself restarting samba 
about 4-5 times daily.  This has reached a crisis point, so any help 
would be appreciated.

In terns of samba version, this problem first appeared when I upgraded 
to samba_3.0.23d-2+b1 (on Debian Testing).  Subsequently, I rolled back 
to samba_3.0.23c-1, but the problem still persisted.  I have since 
upgraded to samba_3.0.23d-4, and am still having this problem.  Please help!
