My PC (only) is loosing connectivity to one server (only) within the LAN

My PC (windows  7) from time to time looses connectivity to one speciffic server. I.e i can't ping that server. This normally lasts a few minutes. During this time i can ping all other servers and my pc can be pinged from other computers. Also note that while i cannot ping this server, it can be pinged from other computers.

Note that all computers, including all servers are i the same subnet and there is no routing involved.

1) Does anyone know what may be causing this?
2) Is there any tool that can help me troublshoot this? Is there a tool like tracert (layer3) but for layer 2  that shows the path that the ICMP packet takes? i.e the switches it goes through?

Thanks

Same subnet?  I don't have a magic bullet, but a few things to look at while it's happening:
I don't know anything like tracert for layer 2...

Try an 'arp -a' from your PC, and record the MAC address of the IP address that corresponds to the server.

What error message does PING give you when it fails?  Is it a timeout (I assume)... not a destination unreachable, right?

The only two things I can think of, off hand, would be your switch arp tables overflowing (which I can't imagine would be specific enough to cause just problems between YOUR machine and a single server), or a clumsy attempt at a man-in-the-middle attack... but that's not to say it's definitely the problem.
