fast nmap scan of XP boxes?

Greetings!

I am using nmap to create a list of targets that I will then use other
tools to test. My problem is how can I do a fast scan of a large (class
B) network of systems running XP, most with firewalling turned on? Will
nmap -sP still find the systems if ping does not?

What I am trying now is a tcp connect scan to the M$ ports. It seems
to find all the systems, but it takes a VERY long time.

Thanx!

-Michael
