I am not sure when it happened. I can guess that it happened when I tried to upgrade from BES 4.1.4 to 4.1.6 and it failed. Or when I did an upgrade of the Endpoint Antivirus, which is our central AV server.
I can see the BES database and it is pointed correctly. It's just the SQL server (SQL express) that doesn't show it.
How do I get SQL to add the database back and get it to running? I can't add any new users. Everything else runs fine.
