Event 36888: The following fatal alert was generated: 10. The internal error state is 1203

I've searched online, but am unable to find any information; why this error is occurring?

It has flooded my Event Viewer: with an interval of 1 minute, this Error keeps popping up. (i.e. the frequency is 1 minute)

I don't have any IIS installed.

This server is purely a Domain controller and no other role has been added.

Please suggest what should I do?

Server OS – Window Server 2008 R2 Standard Edition.
