Need tips & stratagies for Wargames

[bnations]

Im participating in a wargame at my school and I need some help. The target host machine is a fully patched Windows XP PRO (SP2) and I can reasonably assume that ports:
7
9
13
17
19
135
445
3389
1030
139

are opeing and listening, the problem is that the windows firewall is on and set not to allow any exceptions, which Im assuming doesnt alllow any inbound traffic unless in response to outbound traffic. We are on an internal switched (cisco) lan and I have access to XP pro 2, fedora core 4, and server 2003 OS's. I need some ideas on how to bypass this the firewall, also would arp poisoning or using a WSUS server to distribute code help me out in any way?

Thanks
