Hi all,
I have been strugling some time to get my SDL3/CDL3 working in Windows7. After all it was fixed by re-enabling all ipv6 settings. This KB describes how:

Just use the one to repair all and voila communication to the dash works again.
In my case I had broken the ipv6 functionality by using an optimization tool to speed-up the notebook. This tool disabled some ipv6 features...
Hope this helps
