Nono, please state the obvious. People often leave out the
obvious, that they think. And it turns out to be non-obvous.

But on the other hand it may be confusing too. Do you mean
that it must be a port that is open in the firewall
but have no listening socket so you get the RST response
from the TCP stack on the target machine (that is supposed
to be Windows XP.  Have you tried other targets? Since you
report having seen SYN in RST out on the target for all
connection attempts it should not matter).
