Win98 Shutdown problems

[Alex King]

We have a problem with Win98 clients not shutting down properly.  We are
running samba at ~40 isolated sites, a mixture of 2.07 and 2.05a on intel
debian systems.  There are usually less than 10 clients at each site.

The clients are set up to log on to an NT domain, and they run a script
generated by the server to mount between 3 and 8 shares from the server,
depending on their group membership.  Ie, NET USE N: //SERVER/NETWORK etc.

I'd be interested to hear from people who are using Win98/samba in similar
setups and whether they are having similar shutdown problems.

Does anyone have any experience at troubleshooting this kind of problem?
Where should I look?  I've already searched mailing lists etc, and I'd
really appreciate a pointer in the right direction.

The problem seems to affect both Win98 and Win98SE, and the Win98SSE
shutdown supliment fix/patch thing doesn't help.  It is intermittant, but
happems more often than not. I've noticed that logging off on a W98
machine and then shutting down with C-A-D and clicking shutown seems to
increase the likelyhood of a clean shutdown, but this doesn't allways work.
It seems to be due to the interaction between samba and Win98, because the
macines in question shut down ok if they are isolated from the network.

This shutdown problem is a serious problem for me, I'd be willing to put
significant effort into fixing it (even looking into the code)  I realise
that the problem is likely be Win98 more than samba, but if there is
anything I can do to work around it I need to do it.

The servers have a mixture of network cards, 3c905, eepro, rtl8138 etc.
The clients are a mixture also, but we have many (cough) presarios with
realtek 8139 chipset ethernet cards.
