NIC Dropping out

[kipcrist]

Having issues where FirstSpot can be up for anywhere from 30 minutes to 18 hours and then the system loses all connectivity with its NICs. Unable to repair/disable or anything. System restart fixes the problem for another 30 minutes to 18 hours. Seems to be a FirstSpot issue (probably with my hardware) because I can't get it to occur unless FirstSpot is installed. Apache continues to work after failure. System log does not record anything.

I have installed an Intel 10/100/1000Mbps PCI PRO/1000 MT Dual Port Server Adapter but have not yet used it because I don't have the license transferred over yet (hoping this will work and prove it's a motherboard issue). The intel did not have any ethernet cables plugged into it during the post recent 'freeze' and so I plugged in a cable to my router and it configured and was able to access the internet without difficulty...so it definitely isn't a System-wide networking issue, just the ports Firstspot is actively using.

Any ideas?
