tcp/ip failure

I have been experiencing a strange problem for the last few weeks on a
clients site that is trying my brain.

One of our servers is dropping off the network for no apparent reason.
The server is used particularily to run an application that sits on an
oracle database. When a particular task is run, namely updating a
maintenance contract, after a few hours the server loses connectivity.
This updating process seems to have a lot of communication going on
between client and server but nothing I would say is excessive just
poorly designed.

I have changed nics, changed cables, changed switches and nothing seems
to have worked.
I have run a network analyzer, Ethereal, and can see when the tcp/ip
stops but cannot see why. It appears that this is affecting network
connectivity but the event logs show nothing to say why.

I have run extensive diags on the server but nothing shows up

Can anyone suggest why tcp/ip would be affected loke this
 
Sound like DNS problem.
Is your server Group Server or domain server?
If Domain server and the stations appoints to ISP's DNS the session can
be loose. For domain environtment the station should appoint to DNS
server, and this will resolve for all of them.
With Group server there is no DNS problem.
