I'm getting the following exception, intermittently, when accessing an [Authorize]'d action. It seems to work some of the time, and then fail other times, but its definitely worse when I login and select the "remember me" button. If I log off, and then immediately log back in, there is no error, so the text below can't be exactly accurate...there's something ELSE going on here, but I'm at a loss to identify it.

```
System.Data.SqlClient.SqlException: 
    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)

```

Heres the full stack trace

### Edit 1

Here's the requested InitializeDatabaseConnection:
`WebSecurity.InitializeDatabaseConnection("UserDB", "tblPortalUsers", "ID", "UserName", autoCreateTables: false);`

### Edit 2

I just noticed something odd in the middle of that stacktrace:

```
   at System.Web.Management.SqlServices.Install(String database, String dbFileName, String connectionString)
   at System.Web.DataAccess.SqlConnectionHelper.CreateMdfFile(String fullFileName, String dataDir, String connectionString)
   at System.Web.DataAccess.SqlConnectionHelper.CreateMdfFile(String fullFileName, String dataDir, String connectionString)
   at System.Web.DataAccess.SqlConnectionHelper.EnsureSqlExpressDBFile(String connectionString)
   at System.Web.DataAccess.SqlConnectionHelper.GetConnection(String connectionString, Boolean revertImpersonation)
   at System.Web.Security.SqlRoleProvider.GetRolesForUser(String username)
   at WebMatrix.WebData.SimpleRoleProvider.GetRolesForUser(String username)
   at System.Web.Security.RolePrincipal.IsInRole(String role)

```

Why is this code trying to create an MDF File? My data lives on a SQL server, with a connection string name of UserDB, defined in web.config as:

```
<connectionStrings>
    <add name="UserDB" connectionString="data source=NORWAY\DEV;initial catalog=SOMEDB;persist security info=True;user id=MYUSER;password=MYPASS" providerName="System.Data.SqlClient" />
    <add name="DALEntities" connectionString="metadata=res://*/DAL.DAL.csdl|res://*/DAL.DAL.ssdl|res://*/DAL.DAL.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=NORWAY\DEV;initial catalog=SOMEDB;persist security info=True;user id=MYUSER;password=MYPASS;multipleactiveresultsets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
</connectionStrings>

```

What would cause it do deviate from the specified DB, and to try and spin up a new MDF to store membership data? Why does this ONLY happen when a user is using their "remember me" cookie to logback in? (I think so, anyway...haven't been able to prove that yet)
