Check your drivers, ive had funny experiences with VMware hosing my connection in the past, i had to disable and re-enable the network cards.

When I worked for ISP, one of our steps seemed incredibly silly but none-the-less it sometimes seemed to fix problems like these. Presuming it is possible (I don't know your network topography) you can try it... short of trying another cable.

Basically the step was to swap the ends. For arguments sake, I'll pretend your cable goes from PC to router. Take the end that is in the PC, put it in the router. Take the end that was in the router, put it in the PC.

Might sound strange but I have seen it work, short of replacing the cable entirely.

If it's a Gigabit ethernet adapter, try turning off Jumbo frames (although they're good) if your network doesn't support them from the NIC's Properties in Device Manager. Try changing connection speed and specify gateway so connection is "Identified".
