If this problem persists, SQL Server reports an error. To enable the ad hoc distributed queries component, use the following method:

Exec sp_configure 'show advanced options', 1
Exec sp_configure 'ad hoc distributed queries ', 1

However, because the ad hoc distributed queries component has security risks, you must disable it after use. The method is as follows:

Exec sp_configure 'ad hoc distributed queries ', 0
Exec sp_configure 'show advanced options', 0
