[NCSA-discuss] a shameful problem

ok, i'm ashamed and embarassed to admit it, but i have one windows server 
that i have to administer.  it's a citrix server running under vmware, and 
here's the catch: i need to run it with a public ip address - no external 
firewall, no nat.

now, on a real server (read: *nix) i simply turn off all services that i 
don't want, verify with 'netstat -an' that only the ports i want listening 
are actually open, and away i go.  on this godforsaken windows box running 
'netstat -an' yields the following (note that it is currently behind a nat 
device, hence the 10.1.1.11 ip):

holy smegging crap, this is what redmond considers "secure"?  the only 
external ports i want open are tcp 80/443 for the citrix web interface, and 
tcp 1494 for citrix itself.  presumably i can ignore the ports bound to 
127.0.0.1 but i don't have a clue about all the others, or how to disable 
them.  if anyone can help me prepare this box for public ip duty lunch 
(including beer) is on me.
