I've inherited the job of maintaining an application which uses a local SQL Server 2008 R2 SP2 Express database as a back-end. I successfully installed the application some months back after upgrading to Windows 10 so that I could start testing and development, but after reformatting recently, I've been unable to get the database running. I'm using the exact same installer, and so far as I can tell, everything else configuration-wise is the same, with the exception that I'm now on a newer W10 insider build.
The application installer installs SQL Server 2008 R2 with the following parameters:
/TCPENABLED=1 /ACTION="INSTALL" /SQLSVCSTARTUPTYPE="automatic"
/SECURITYMODE="SQL" /SAPWD="password" /INSTANCENAME="app"
/FEATURES=SQLENGINE,REPLICATION /BROWSERSVCSTARTUPTYPE="Automatic"
/SQLSVCACCOUNT="NT AUTHORITY\NETWORK SERVICE" /IACCEPTSQLSERVERLICENSETERMS
/INDICATEPROGRESS /QS
The installer is built using Advanced Installer, and is configured to run a database setup script after installation has completed, but when it reaches this step the database times out and the install fails. To test the database I tried using a UDL file, and though the database itself is visible, when I attempt to test the connection I get
"Test connection failed because of an error in initializing provider. [DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied."
I've tried absolutely everything I can think of to fix this problem. I've removed all traces of every version of SQL Server from my computer, purged the registry of any remaining keys, and deleted any remaining directories. I've checked and restarted all SQL services, tried different SQL service accounts, different versions of the SQL installer, ran the installer(s) as an administrator, ran them in compatibility mode, and checked log files. I haven't found anything helpful on StackOverflow or on Advanced Installer's forums. Nothing's worked, and I'm completely out of ideas at this point.
