I setup an application + SQL Server on AWS. Everything works fine my SQL User can read/write to any table.

Now I connected to the SQL Server using my domain admin account using windows authentication in SQL Server. It works fine and I can insert / update / delete rows. But as soon as I try to edit a table using the interface, meaning select "Edit Top 200 Rows" I get the following error:

The requested operation cannot be completed. The computer must be 
trusted for delegation and the current user account must be configured to 
allow delegation.

Trusted delegation

In the local Security Policy I have enabled domain Admins and also my exact account to the following and also all admins:

Enable computer and user Accounts to be trusted for delegation

Enabled Account

What else am I missing? I use SQL Server 2014 Standart on Windows Server 2012


OK, I think the Work Around mentioned at serverfault.com/questions/696804/... is a very valid answer so I am listing it directly here. I have the exact same issue in Microsoft Azure (editing a table SQL Management Studio).

I fixed it by setting DWORD regkey ProtectionPolicy to 1 for the sub-key HKEY_LOCAL_MACHINE\Software\Microsoft\Cryptography\Protect\Providers\df9d8cd0-1501-11d1-8c7a-00c04fc297eb
