Hi, I have the same Problem. I had a Web Application. It was developed in ASP.NET , C# , VS 2008 and SQL Server 2008. I am using connection string as
"Data Source=xxxx;Initial Catalog=xxx;Integrated Security=True".
It is working fine, when I run it from the Visual Studio. When I run it from the Internet Exlporer(After Creating Virtual Directory), I am able to access the Home Page. When I provide the User name and Password in that page and click on Login Button, i.e., at the time when it is hiting the Data Base, I am getting the Same Error. The Error is as Follows
Server Error in '/SriVariVevaCell' Application.
Login failed for user 'NT AUTHORITY\IUSR'.

I think the Problem was in Connection String. I using the SQL Server Windows Authentication. Please Help me ASAP.
Thanks in advance.
