Migration to databases Domain Users do not have access I migrated databases to new servers, however the applications that were previously used with the databases are failing to load. I have changed the connections and etc. The jobs also seem to be failing. I have a domain account who is the job owner. However, when I try to execute the job under my username I get the following error:


  Executed as user: NT AUTHORITY\SYSTEM. Login failed for
  user.....[SQLSTATE 28000) (Error 18456).


Is this related to Domain Users not having appropriate read and write access to the database? 

How would I give all domain users permissions to execute stored procedures.
Users are tied to logins with SIDS. If you moved your DBs, you may need to recreate that mapping.

You can either create another login for DOMAIN\DOMAIN USERS and go through and manually remap, or
run sp_revlogins (link) and sp_change_users_login 'Report' (link)

If sp_change_users_login 'Report' finds orphans, run sp_change_users_login 'Auto_Fix', 'user'.
