(Just posted to the news sections in these Workspaces)

If you're running wkssync or wksalone on a machine that's not previously been used with the VS.NET provider for Workspaces, you need to do one of the following

• Run the VS.NET provider installation package

or

• Create the registry key 'SOFTWARE\Microsoft\Windows\CurrentVersion\\Internet Settings\Passport' and add a string value titled 'LoginServerURL' that points to 'https://login.passport.com/login2.srf?lc=1033'

That should resolve any exceptions being thrown during the passport authentication stages.

Thanks Ethan!
