Hi Many thanks for the help, the above information was not quite enough to get me going, however it did provide enough of an insight to get me started.
TBH I don't think a followed it exactly and I didn't realise about the importance of the 2 different /64 ranges.
Looking at the regedit part I did some research into that and found that all the IPV6 elements are enabled by default. Therefore DisabledComponents key is not required however if it is created it should be a DWORD value rather than a STRING.
The other thing I noticed was the HE DNS entry in the code had an extra 0 added, checked my tunnel details and I used 2001:470:20::2 instead
I did also find this thread http://www.tunnelbroker.net/forums/index.php?topic=1439.0
Which gave me clearer instructions and a step by step guide to setting up the route advertising, I still have not got all the kinks worked out however, though I do now have the laptops WLAN IPV6 configured manually to use one of the LAN side IPV6 values and use the desktop as a gateway, so now provided the desktop is running both computers score 10/10 on test-ipv6.com
Many thanks for your input
