I looked into this and the problem is not with the firewall.
The issue is that DirectPlay is deprecated on Windows 8. As a result the 
libraries are not installed by default and when an application tries to 
load them one gets a dialog that says:

  An app on your pc needs the following windows feature
  DirectPlay

This then offers to install it and the application remains stuck until 
the user says yes or no. That's why the test times out.

One option would be to trigger this dialog so DirectPlay is installed. 
This dialog will then no longer be triggered and the test will run fine. 
That's what I have done on the w864 VM some time back.

However it may be better for the test to detect that the dll is missing 
and to skip if that's the case. Otherwise even if I fix the issue on 
this VM we'll still get failures from any other Windows 8 system for 
which the user did not go through these steps.

I suspect a simple LoadLibrary() will trigger that dialog too so some 
other approach may be needed. Maybe something based on FindExecutable() 
would work.
