Verify the database server

Log in to 

Microsoft SQL Server

 Management Studio as the NGAD user.

Verify that the NGDeliverylog, NGDelivery, NGDeliveryAccount, and NGDiagnostics exist on the same database server.

Check the database directory and verify that there are files for the database installed on the server.

Open the ngdelivery database to verify that the Service Broker is enabled:

Select from the dbo.AsyncSqlQuery table.
In the query results, check the following values:
LastRunOn
 should be close to the current time.
LastRunOK
 should be ‘1’ 

If the service broker is not enabled, run the following query: 

alter database RestoreDBName set enable_broker with rollback immediate
