Old Application

Post by GNiessen » Thu 21 Jun 2012 13:39

We have an old application that is still used that appears to be developed with the connection Options.Provider = prSQL. It is a Windows Form application and is trying to use windows authentication. It runs fine on most machines, but now is not working on a newer Win 2008 R2 server. The Native Client is installed on that system.

But we are getting a error connecting: Login failed for user ''. The user is not associated with a trusted SQL Server connection.

Due to some missing components, we cannot recompile the application with more debug or different connection options. What drivers is it needing? Or is there something else we need to do to get it to Trust the connection? The user has Administrator rights.
