IPv6: Leopard, Win2003

[rhtvkm]

Hello.

I have two computers: PC and iMac. I want to connect this two computers by IPv6 protocol. Computers connected with patch cord. IPv4 working perfectly.

On Windows 2003 in "Network connection properties", I add "Microsoft TCP/IP version 6" and disabled "Internet protocol (TCP/IP)".

On Mac I try to ping6 Windows IPv6-address, and have a good ping result. When I try ping iMac from Win2003, I have error: "Destination net unreachable".

Also I setup IPv6 web-http server on Win2003, and I can't get access to server from Mac.

What I am doing wrong?

Thanks. And sorry for very bad english.
