Hi guys I'm trying to connect to a MSSQL database with ASP.net! I've created a Database containing 3 tables, but every time I try and connect to the database I receive an error message stating I must obtain permission first... How do I connect or get the permission?

Windows Authentication

you do not have permission to open this file

contact the file owner or an administrator to obtain permission

Answer 1

You can adjust your string connection with IntegratedSecurity = true

Link : http://msdn.microsoft.com/fr-fr/library/system.data.sqlclient.sqlconnectionstringbuilder.integratedsecurity.aspx

Nota : information current Windows account credentials are used for authentication

Nota : you can also use server account (false), but you must specify in your string connection

Answer 2

Try something different such as enabling "SQL Server and Windows Authentication mode" in SQL Management Studio
Right click the Server node => Properties => Security

Then create a new SQL user profile with full permissions to your database and use those credentials in you connection string.

Answer 3

您的应用程序池标识必须具有足够的权限才能访问您的数据库。
