Additional Information

Lan Traces revealed that they are having problems with a workstation enabled firewall. It is not allowing ACKs to be returned for half-open TCP/IP connections. Instead of SYN | ACK | RST, the client and server are doing SYN | ACK SYN | ACK SYN | ACK. And the client is failing to connect due to the firewall blocking the ACK packet.
Also check for any kind of firewalls that can block ACK packets.
