I have installed the reporting component on a primary server (10.1.0) without any errors. Connecting to infoview through the zenworks control center also works perfectly. When I want to run a query a database error message appears, login failed for ...@zzz.zz In the event viewer of the external MS sql is the following event created:

Login failed for user '...@zzz.zz'. [CLIENT:]

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

However, this user is db-owner of the database ZENworks... What's going wrong?
