I'm running RHEL ES (kernel version 2.4.21-27.0.1.ELsmp), and have

network provider or something wrong with the server.  The tests on the
network so far have been inconclusive but points to a server issue.

This really smells like a duplex problem. If you're at 100mbps, force the interfaces on both ends to be 100 mbps full duplex. Do not rely on autonegotiation since it will frequently get it wrong.
