LAN disconnects automatically

I have a mac book pro that since Thursday, all of a sudden, it disconnects from the LAN.  The wifi works fine.
I replaced the network cable and the 5 port switch that it was plugged into. I have also tried a different computer with the same cable, and
it didn't disconnect with a different computer.   Since a different computer works fine with the same network cable, I'm thinking there's an issue with the MAC.

I don't use MACs much, so suggestions I can try to isolate the issue?

I'm currently using DHCP with windows servers.  I have about another 9 or 10 MACs on the network, and no one else reported any issues just yet.

Thanks. D
