Login failed for user. Microsoft SQL Server, Error: 18456

Hi,

I have a windows 2008 with SQL Server 2008 R2 VM on Azure. I am trying to connect to the SQL server for the first time using SSMS, but have not been able it. I have a VPN tunnel, so I am connecting using Windows authentication. The error I get back from SSMS is:

Login failed for user 'domain\username'. (Microsoft SQL Server, Error: 18456)

In the event viewer I see this error message:

Login failed for user 'domain\username'. Reason: Token-based server access validation failed with an infrastructure error. Check for previous errors. [CLIENT: <local machine>]

I have done the following:

- created an endpoint for port 1433

- opened port 1433 in the firewall

- Ran the MSSQLSERVER service as the build-in users Network Services, Local System, and Local Service, and as a local and domain administrator, with the same exact result each time.

- I get the same result trying to connect locally or remotely.

- I get the same result trying to connect using sqlcmd.

- None of the suggestions in the related worked.

Any thoughts on how I can resolve this issue?

Thanks,

MH
