As of right now, DotRas is not Windows 8 ready. As such, it's not a supported platform by the project but it is on the project roadmap for v1.3.
If the Windows 8 release experience is anything like Windows 7, I won't be updating DotRas until after Windows has launched. Yes I realize I'll be behind the power curve, but when Windows 7 was released a number of changes to RAS were in the product right
before launch and then pulled which I would have needed to fix before I could release the next version of DotRas. As Windows 8 gets closer to release I may start implementing pieces I don't expect to change, but at this point we're too far from release to
make that commitment.
As for the problem you saw, you may want to try elevating your application privileges. During the Windows 7 release, a large portion of the Win32 RAS API was placed under control of the UAC which it would make sense they have added even more of it for the
Windows 8 release.
I agree with you completely, and I have some good news actually.
The error was exactly about the lack of application privileges. I'm trying a lot of DotRas features on Windows 8 since yesterday and they all seems to work perfectly.
I guess you won't have any big troubles updating it after Windows has launched. However I'm also pretty sure that nothing or nearly nothing will work on Windows 8 Metro Apps, since it's using a completely new set of API's (WinRT).
Anyway, thank you for the support.
