So basically, I developed this ASP.Net MVC application on a Windows 7 box with Visual Studio 2008. It works well on the local machine, and I was able to host it in IIS no worries. I then decided to upload it onto subversion, and fetch it on a different Windows Server 2008 machine. I downloaded it, had the IIS document root point to my application folder, and started it up.

I can visit the site fine. However, as soon as it needs to do anything with the SQL database I get the following error:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

My ConnectionString to the SQL database is as follows:

    <add name="UserClaimsConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\UserClaims.mdf;Integrated Security=True;User Instance=True"
  providerName="System.Data.SqlClient" />

The error throws a wobble about allowing remote connections, but the database is local! Additionally, when I look at the StackTrace of the error, I see something odd at one portion:

OpenIdProviderMvc.Models.ClaimRepository.ResetAutoSend(String upi) in C:\OpenIdProviderMvc\Models\ClaimRepository.cs:40

The directory which it is referring to happens to be where I had it stored... on the development box! It is stored in a different location on the Windows 2008 server.

Where have I gone wrong in migrating this project?

EDIT: Here is the full stack trace to provide a bit of additional information.

The path in the stack trace probably points to some path on your dev machine because that is what is in the .pdb files (have they been added to subversion?). I don't think this is related to the connection error and you will probably have to sort that out separately.


You need to install SQL Server 2008 Express on the server if it is not already installed. ASP.NET needs sql server express installed to attach the mdf database file in your data directory.

You can download it here
