The way this looks from here, the connection stays in your machine - i.e. your
machine (192.168.1.107) connects to your machine (again 192.168.1.107) using
ssh through a loopback port forwarding tunnel.

Not sure, but could this be an IP/port conflict.  What happens when you
stagger the port Nos (i.e. vnc server on 5900 and vnc viewer on 5901)?

I am assuming that WinXP box has a different IP address, hence no conflict.
