Show us the log entries.

It is likely the Windows machine is hanging up for a reason.

check 'ipsec --version'. If using KLIPs, you need to have the natt-patch
applied. otherwise you do not. The startup messages in the logs will
tell you if nat-t was detected or not.

"openvpn" is not ipsec, so you can't mean you are connecting openswan
to openvpn.  openswan 1.0.7 is old, is lacking various security fixes,
and the entire openswan-1 series has been EOL's a while back
