Pardon my confusion, but I take it that this user is trying to serve up his Tinycore desktop from a Windows computer? If so, this is what works for me.
Install on the TC machine:
x0vncserver.tcz
To configure it, follow instructions found in the apps manager exactly.
On Windows machine, install something like TightVNC (either whole package or at least the viewer), or UltraVNC, both work fine for me. Enter IP address of server, and enter the password that you configured on the TC box.
