I have a user with a machine that complains he cannot receive email. I remoted into his machine and found that he cannot ping either the incoming or outgoing mail server from his machine. In fact, it seems as if he cannot ping any websites. The few I tried all came back as requests timed out. The user is able to get online. I was not able to ping his machine from mine. The user went to a machine right next to his and was able to ping the incoming and outgoing mail servers without a problem.

I've flushed the DNS cache and rebuilt the TCP/IP stack. I'd appreciate any help with this matter. Thank you.

If his co-worker right next to him is working fine, I might have them both do an ipconfig /all and compare IP subnets, Gateways, DNS, WINS...and see if they differ any. If they do -- make the changes accordingly.

If that doesn't resolve it, might try static IP and specifying DNS Server or vice-versa with DHCP -- whichever is the opposite of what they have.

Seems much more like an error in the DNS entries or ...

Did you also check if there is any FireWall/AntiVirus activated on the machine ? Most FireWall are blocking incomming/outgoing Echo request.
