Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed.
I had to uninstall and reinstall SQL server 2005 and Express on my development machine. After the un-installation, I reinstalled SQL 2005 standard then SQL Express. When I tried to open a SQL express database in VS2k5 I got the error “Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed.” After much searching, I found out the solution.
- Open SQL Server Configuration Manager. Navigation to Start > Microsoft SQL Server 2005 > Configuration Tools > SQL Server Configuration Manager
- Double-click SQL Server (SQLEXPRESS) and change it to use LocalSystem
- Delete the folder
Windows Vista: C:\Users\[user]\AppData\Local\Microsoft\Microsoft SQL Server Data\SQLEXPRESS
Windows XP: c:\Documents and Settings\[user]\Local Settings\Application Data\Microsoft\Microsoft SQL Server Data\SQLEXPRESS

That’s it.
Does that fix your problem?
