Workstatons lose connection to server overnight

[Guest DBCallaghan.SpmOff@googlemail.com]

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.
