Mapped drives are disconnected

I have a 2003 server with XP clients. The XP clients throughout the day are
being disconnected from the mapped drives on the 2003 server. I have changed
the lanmanserver parameters in HLM/Sys/CCS/Services to be ffffffff of the
autodisconnect on the XP machines but this has not helped the problem as
found in Q297684 of the KB and I do not use group policies.

Is anyone else having this kind of issue? Is it an XP issue or a 2003 issue?
It is driving me crazy and need help fast!

Thank you from a crazed IT.

 

Update the drivers for the network card.

The problem may be SMB signing or LAN Manager authentication level. In
Windows 2003, default server policy forces all SMB traffic to be digitally
signed which seems to cause a problem in some configurations of XP Pro. In
Local Security Policy (Start > Run > secpol.msc > OK) navigate to security
options (Security settings > Local policies > Security) and try disabling
the option for Microsoft network server:digitally sign
communications(always). Ensure you do this on all machines involved (such
as via a GPO for an OU). Run gpupdate /force on the server after making the
change and do the same on the client machine afterwards.

Security settings that can cause a problem with downlevel client access:

I made these adjustments on my server and on one XP Pro machine. The XP
machine did not have these policies configured, so I disabled them. I have
made this machine my "controlled environment" machine to see if this works.

Will this work even if one of the mapped drives is to a SCO-Unix machine?

I will keep you posted. Thanks for the information.

Sorry to take so long to reply.
I did as you said on my controled computer and it did not help. The Unix
machine still disconnected from the XP computer. As long as the user "logs
off" and back on then they are fine.

Any other suggestions? I am starting to install more XP machines that will
connect to this Unix box and can't have this continuing to occur.

Thanks for any help
