Hi All,
I am developing MVC 4 application with Entity framework 6.0(Code First Model) on .Net framework 4.0. I was able to connect sql server using sql server authentication but I am not able to connect sql using Windows authentication.

XML

<add name="ConnectionString" providerName="System.Data.SqlClient" connectionString="Data Source=servername;Initial Catalog=DatabaseName;Integrated Security=True;MultipleActiveResultSets=True" />

I checked logs and I found Eror is "

C#

The underlying provider failed on Open."

if you guys have any idea ..please let us know

What I have tried:

I changed IIS Settings Impersonate to true and sql server configuration settings. but SQL server authentication is working but not windows authentication

check your server instance.

You have to switch your SQL authentication to mixed mode (Both SQL and Windows Authentication)

The only two options are Windows or Mixed. If it was working with SQL authentication, then it's already set to mixed.

Thanks for clarifying Richard.

Did you try with Integrated Security=SSPI because Integrated Security=True may not work with all providers

Where is it running? in your environment or some hosting provider?
