Integrated NIC turning off for no good reason. Have to pull power cord for 5 minutes to reset.
We have noticed this problem primarily with GX150's, but it has occurred with 240's, 260's and 270's. (And this means that it is a mix of NIC types demonstrating this issue.)
The problem is common enough to be noticed and somewhat, but not completely and reliably replicable.
The problem rarely, but noticeably occurs on Windows XP machines that have been running for a while. Literally, the power goes off on the NIC and the operating system has no reference to the NIC, even after booting. If you look at the back of the machine, the lights are off despite the BIOS settings being set to have the NIC properly on (as we plan to use WOL). The only way to get the NIC back is to pull the plug from the system and let it completely be without power for about 5 minutes.
More noticeably the problem occurs when reinstalling the OS onto a machine... After the sysprep finishes and before the OS comes up in it's complete form, this NIC will just shut off. Sometimes you can get the same machine to do this a few times in a row, even when switching buildings
This problem is not isolated to any particular segment, subnet, switch type...

Also, I'd recommend posting this in the Optiplex - Network forum. This is a conference for Dell Dimension desktop systems, which may not contain the information that you need for your specific model.

Okay, the first is not really much of an option given that the majority of the issues occur before XP is fully up and running. In the cases where this occurs, XP does not see the card as existing at all so there is nothing to set. This is true even in the cases where the box had been running for some time and the issue happens. Since we have no clue, on the boxes that are running, which boxes will develop this failure, there is really no way we can proactively set up an appropriate test group with the different possible settings without being disruptive to the main line of business.
PortFast is already set on the switches. Further, we had already monkeyed with the switch settings for the port duplex/speed on the switch and altering none of those settings appeared to have any effect on the problem.
What we need to know is what kind of situations could cause the network card to off itself like that? Power spikes (this may be ruled out given how well we have protected the environment), certain network packets....
