I installed RHEL ES 3.0 on an Intel box. The install went smoothly and I am at the point where I can do just about all I need. I want to ping an Windows 2000 server but I get "Destination Host Unreachable". I try to ping the Linux box, but get 'Request timed out'. I am able to ping all other machines from other domains but the Linux and Windows server aren't talking to each other. The IS / network team suggested that because the network is doing 100T full-duplex, the servers may not talk to each other (It is my understanding that the network auto negotiates, but that's another story) and I need to configure my eth0 card to do 100 Full instead of 100 Half Duplex (the messages file confirms that I am doing 100 Half Dup on the Linux box). Is it possible to force the eth0 card to do 100 Full on a auto negotiating network like the Windows box? If so, how? Thanks! -X </BODY> </HTML>
