Cannot Generate SSPI context

Hi guys,

I have a weird error I cannot resolve.

Setup:

Windows 2008 SBS server running SQL express 2014, Services are using a Domain Account with privileges.

Problem:

Client computer on the same domain as the SQL. Using the ODBC to create a user DSN sometimes works and sometime just disconnects and when I try to configure it again I get Cannot Generate SSPI Context.

If I restart the server it most likely will work again but then at some point will just disconnects and return this  error again when I try to reconfigure.

I can't seem to pinpoint this error to anything specific.

Any ideas please???
