Resolution

  1. On the Orion server open database manager and click add default server
  2. Double click the table's Credential and CredtialProperty and click execute query
  3.  Locate Orion in the value column and see what CredentialID it is and check in the credential table and see if it corresponds to CredentialOwner "RabbtMQ"
  4. Delete the account in question from the credential property and credential table more than likely the RabbitMQ account
  5. Rerun Configuration Wizard.
