​During a ConfigMgr Installation, it was found that the Computer Account did not have the correct permissions to the SQL instance.

In order to add the Computer Object, use the query below (run against master).  You will then need to add the correct User Mapping within the SQL Security of the Account to have proper permissions to the ConfigMgr DB.

NOTE: Change DOMAIN\SERVER01$ to your Domain and Server

CREATE LOGIN [DOMAIN\SERVER01$] FROM WINDOWS WITH DEFAULT_DATABASE=[master], DEFAULT_LANGUAGE=[us_english]
