Thanks for claryfing the URL aspect.
While reading your reply I might have discovered my problem, if it is 
one at all.
Unfortunately the display machine is located in a different network than 
the capture machine, so they are not within the same local subnet,
which I assumed shouldn't be a problem assuming the ports
are opened for the capture machine's subnet (eg. 11000 for the service 
manager, and possibly ports for the services). Is this assumption correct?
