[cifs-discuss] Spontaneous SMB session failure

[Afshin Salek]

Is CIFS server running in domain mode or workgroup mode?

Are you connecting with the same user or different users from
these XP workstations?

Do you map the shares manually and with no problem?

There are a number of XP workstations operating on batches of files, using the the PeerNet Tiff Printer driver to print to files on shares on the CIFS server.  These workstations are continually creating new files on the server using UNC names, resulting in new SMB session for each file created.  The client machines run for a time until they get an access denied error.  I have not been able to find any log entries on the server relative to this, but a network snoop shows the following:
