Question : Losing Network Access

We have one particular PC on our LAN that is acting up. It was running Win2k with onboard 10/100 NIC, static IP.

Every day or two I'd come in the morning and find that the PC has lost all connectivity. I can't access any network resources and can't get to the internet.

After a week of struggling with this problem I upgraded the PC to XP SP2 *and* put in a different PCI ethernet adapter. I have also changed to dynamic ip addressing. I am continuing to see the same problem!

I see nothing relevent in the event logs except this one message....

Event 1003:
Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address .  The following error occurred:
The semaphore timeout period has expired. . Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.

Even with the new OS, new NIC and dynamic ip addressing...it still continues to lose connectivity every 24-48 hours.

The only way to bring it back online is either to reboot, or to disable, then re-enable the NIC from the network properties....any ideas!?

Answer : Losing Network Access

This may be as simple as the controller and/or the network adapter were pushing to much at the same time, I would setup the backups to not overlap and see if this corrects it over a coupe of days.
