I've created a new SQLExpress database to be used as a published feature layer. I open the ArcGIS Server Properties to register the database, but when I click "Add" next to "Publisher database connection", nothing happens. It used to work for me & still works for my GIS Mgr on his computer. We did have all of our software upgraded from 10.4 to 10.8 several months ago & I don't believe I've tried this process since. Our permissions are mirrored, so that's not the issue. I can see & validate all existing registered databases from my computer as well.
Wondering if I need to have ArcMap Desktop uninstalled & re-installed? Anyone else experience this issue or have any guidance?
