Hi!

Jeremy is correct. Disabling IPv6 on Windows 7 is a very bad idea (since
the stack is an IPv6 dual stack and some features require IPv6). The
problem is most likely to be name resolution.

Your could test connectivity using literal IPv6 address on Windows 7
rather than a name, thereby avoiding name resolution.

Best Regards,
David
