Hi,
While I was troubleshooting, I used Microsoft NetMon to check the port Client tool was trying to connect and fail apart from the port that were opened for connection.
-----------------------------------------------
Install Netmon or Wireshark on both the pc (working and not working).
Note: not working stands for not able to connect to UDT
Check the communication for UDT designer process with Server on both the PCs.
You get the list of ports to which it is connecting to BO Server. You will see some difference in the communication of working and not working PC.
Take a note of all the ports of the BO server that were involved in the communication of UDT on working PC.
On server check the services that are using these port OR telnet these ports from your PC to BO server.
This will give you clear understanding of the background communication and you will be able to eliminate the problem.
