Hi

This is a similar problem to others seen here like "Workstations lose
connection to server after 10 hours" BUT I can't follow even the first
instruction as we don't have a internic approved domain name.

Here's our problem:

We leave our PCs switched on and logged in overnight.

During the night our PCs lose their network connection. On re-booting
the PCs login and regain their network connection with no problems and
work fine throughout the day.

The PCs have all their power saving features disabled and in
particular have the power saving features of the network card turned
off. All power saving features of the server are also turned off.

Some newsgroups suggested moving the DHCP function of the external
router onto the server, which I have done, but this has not cured the
problem.

Please can you advise what I should try next.

Thanks

Why do they need to stay logged in?
Not really enough to go on...

What are the exact symptoms?
Can they ping the server when this happens? Can they ping anything?
What do you see in the event logs?
What server OS & SP level?
What client OS and SP level?
Do you use AD?


Personally, I don't recommend leaving workstations logged in overnight
anyway - I tell my users to reboot before they leave and turn off their
monitors. I want all files, profiles, and connections closed for my backups,
for any after hours server work I might need to do, etc.
