Ethernet networking connection dropping every ~40 minutes

I have done everything I can find including uninstalling all virus checking
programs after checking for viruses, resetting the Winsock. I downloaded all
the SP2 updates and everything. But no matter what I do my ethernet
connection is interrupted for like 2 seconds every 40-50 minutes. It
reconnects instantly but whatever I was doing that requires a constant
connection instantly disconnects. This is getting very frustrating so please
if anyone has an idea I would appreciate it...

OK... a shot in the dark.
It's possible that you are getting IP address leases that last 40-50
minutes and when that time is up, you lose your lease and your IP
address is lost and then a couple seconds later is re-obtained.
Under normal conditions, the lease is renewed after it is 1/2
expired but sometimes misconfigured firewalls prevent this.

To test for all this:
o Bring up a command window (start->run->cmd)
o Enter the command:
ipconfig /all
o Note the times in the "Lease Obtained" and "Lease Expires" lines.
The current time should never be more than halfway between these
two times.
o Enter the commands:
ipconfig /renew followed by:
ipconfig /all
o Verify that after completing the ipconfig /all command that the
"lease obtained" time corresponds to the time that the /renew
command completed. If it does, then this isn't your problem.

You don't say whether you have a router between your computer and
modem. If you do, the router itself also negotiates an IP lease
from the modem and can have the same problems. Check your router
configurations.

Good Luck,
John
