By default all the Condor services except for the condor_collector run 
on dynamic ports.  The condor_collector runs on a standard/well-known 
port of 9618.  The idea is client can do a query to the collector (just 
like condor_status does) in order to discover the IP address and port of 
other services in the Condor pool, like a condor_schedd.

So you should be able to do something like open a browser to
  http://my-central-manager.com:9618
and see something.  (probably a soap fault saying http file not found).

Now, if you do a "condor_q", at the top is will list the port that the 
schedd dynamically bound to.  Use that port to test talking to the schedd.

I said the schedd uses a dynamic port by default.  You can change this 
to use any well-known port you select via the condor_config file.  To do 
this, lets say you wanted the schedd to use port 8080 - put the 
following into your condor_config file:
  SCHEDD_ARGS = -p 8080
and then do "condor_restart".  The above tells the condor_master (which 
starts all the other Condor services on a machine) to invoke the schedd 
with the command-line argument of "-p 8080", and the "-p" switch to any 
Condor daemon is used to tell it to listen on the well-known port specified.

If you actually want to try out using the SOAP interface, that is hard 
to do with just a browser.  A couple weeks ago I posted to this email 
list a simple perl script that acts like a trivial "condor_q" - see 
https://lists.cs.wisc.edu/archive/condor-users/2008-March/msg00067.shtml

On Linux, you could prolly run the Perl script I posted above as-is.  To 
use the above script on Windows, you will of course need a Perl 
interpreter installed on your Windows box.  Most Windows folks who use 
Perl like ActiveState Perl --- last time I checked, this Perl release 
came pre-installed w/ the SOAP::Lite package.  SOAP::Lite is a popular 
Perl library that allow Perl scripts to easily communicate with web 
services.  See 
http://aspn.activestate.com/ASPN/docs/ActivePerl/5.8/lib/SOAP/Lite.html

Hope this helps
Todd
