[jcifs] JCIFS and Windows 2003 HP Storage Server

[Andrew]

Hello all,

I am not a developer but an end user using an application that employs JCIFS. 
We are troubleshooting an issue involving Windows client stations using JCIFS to
access multiple file shares on an HP Windows 2003 Storage server.

The client application launches and when the first file is opened, it mounts all
the volumes it needs as specified by a central server.  These include two sets
of volumes, those hosted on a Solaris system and those on a newly implemented
Windows system.  Occasionally, the Windows system volumes, which are intended to
be persistent, fall off, apparently due to reset packets sent by the Windows
host.  Why these reset packets are sent is not understood.  Solaris based file
acquisition stations that write to that Windows storage system are not
disconnected from those same volumes.

Here are some line items:

A ) Windows clients using a Java app that employs JCIFS to reach a WIndows CIFS
file share have intermittent reset connections that doesn't seem to relate to
idleness.

B ) Solaris clients using those CIFS file shares do not have reset connections.

C ) Windows clients using JCIFS to reach CIFS shares on a Solaris system do have
not reset connections.

D ) HP Level 3 support finds nothing out of the ordinary with packet traces, the
operating system, or the server hardware.  

E ) App vendor is not motivated for troubleshooting, since the new Windows
system is customer implemented and doesn't work, and the Solaris system is
vendor implemented and does.  Their opinion, is of course, fix your NAS.

F ) For what it's worth, TCP offloading is disabled.

G ) "Regular" Windows client connections do not seem to be affected.

Any suggestions you may have are appreciated.  We've been at this for a few
weeks the NAS project is in jeopardy.

Thanks in advance,

Andrew
