Look as I might, I can not find a thread related to failed SQL Logins.

My gut tells me it is on our end, but I'm not totally conviced.

I've been Admining SharePoint for a long time and am not sure why a service account can be used to do the add-on install, but not be used to query data from the the created DB.

This is a development instance, so I only use one service account throughout.

Any assistance would be greatly appreciated. I don't mind finding out I missed something in the install. After being in IT for 30 years, I have no pride.
