I am not sure I fully understand the issue, but you might try a configuration marco which adds condor as an exception to the firewall:
ADD_WINDOWS_FIREWALL_EXCEPTION  
When set to False, the
  condor_master will not automatically add HTCondor to the Windows
  Firewall list of trusted applications. Such trusted applications can
  accept incoming connections without interference from the firewall. This
  only affects machines running Windows XP SP2 or higher. The default
  is True.
