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.
