I had to deal with the same problem this week when trying to register for a download to evaluate the current version.However, the issue seems to be fixed, since today it worked as expected.Greetings
It's a known issue. This will happen if your BuildService is running with a local account such as “NT_AUTHORITY\Network Service”. Set your Build Service to run with a domain account and this error will go away.https://blogs.msdn.microsoft.com/girishp...
