Description Michael Harlaut 2004-03-10 07:26:48 UTC
Versions : 
- Debian stable
- Samba 3.0.2a
- Windows 2000 SP4 client
- NT4 SP3 PDC
- No WINS

Problem description :
- Clients lose connection with the mapped drive

Reproductibility :
- Almost always

How to reproduce : 
- Copy a 50 Mbytes folder from the desktop to the mapped folder
- Delete it (on the server)

Result :
=> The folder is well deleted, but connection is losted
=> File explorer returns an error saying the drive no longer exists
=> When trying to reconnect to the drive, Windows says the drive letter is
already existing.

After a short time (a second), the reconnection is possible.

Comment 2 Michael Harlaut 2004-03-16 08:20:56 UTC
Here is the log concerning this problem.
http://bogus.harlaut.net/samba/smb-connectionlost-log.zip

We now fully reproduce the problem, but only with Windows 2000 SP4 Client.
Win 98, NT, and 2003 are not concerned.

what's more, Samba 2.2.8 is concerned too ! (?)

We haven't tested yet with other SP than SP4.

Hope this helps ....

t is not a Samba bug :-)  

We do not have to find the problem but the problem is specific to the map drive
(F:,G:,..)

During the copy removal of files a red cross is on the map drive and the
connection is loss (Error message Windows)

The reproductibility of probleme is :

 Windows 98   ==> No problem
Windows NT (SP3) ==> No problem
Windows XP pro SP2 ==> No problem
Windows 2000 SP4 on the Dell Optiplex GX 260 ==>  Alway
Windows 2000 on the other computer ==> No problem (same SP4 and Hotfix on the
Dell..!)
Windows 2003 ==> No problem

We do not have used the map drive on then Dell and Windows 2000 SP4 !

Thank you for your assistance

Thanks for the update.  I'm assuming that both or you work 
together since your email's are from the same domain.
Closing.
