Config looks OK, in fact certainly looks like you've copied the sample config here (going by your use of IP pools):

http://www.cisco.com/warp/public/110/pptppix.html

What is error 721 again? Check your PPTP packets are even getting to the PIX, you should be able to "debug vpdn" or "debug pptp" or one of those (can't remember the exact command), that'll tell you if the packets are even getting there.

Yeah, I did copy that config and added a few other needs.

Error 721 Remote PPP peer is not responding.

Thanks, I'll try debuging and see what messages I get...

For everyone's reference in case your XP clients do get error 721 when trying to VPN in, make sure that if your using Win2K server that it has the latest service pack (4) on it.
