Condor Black Magic
From Ben's Writing
The Windows Firewall
On Windows there is a pesky firewall feature that is on by default. Condor has a system to bring up its support services (i.e. anything other than the master service), after the master has been started, once a hole has been "poked" thru the firewall. This logic, however, fails if a user has disabled the firewall shipped with Windows. The result is that the support services take an increasingly long time to come up. To remedy this, one can add the following entry to the condor_config file:
ADD_WINDOWS_FIREWALL_EXCEPTION = False
This will ensure that the firewall poking logic will be skipped and the support services will be spawned immediately.
