Login failed for user NT AUTHORITY\NETWORK SERVICE

I have built a web page in visual web developer express and I moved it over to use IIS. I gave NT AUTHORITY\NETWORK SERVICE read and write permissions to the folder and included it in my IIS virtual folder. I can see the login page just fine. I can create a user just fine. I can even access the forgot password page just fine. But if I try to login in I get this stack trace. I can't figure out what more I need to do for NT AUTHORITY\NETWORK SERVICE. Can any one help.

Server Error in '/' Application.

Hi matt,

You have using Integrated Security=SSPI in your connection string. You would have to use: User ID and Password.

Good Coding!

This is a common login failure when the application runs under IIS, and the 'NT AUTHORITY\NETWORK SERVICE' is the account used by IIS6.0. You may take a look at this post:

sql

login failed

I know this is probably a question that has been answered a million times, but it is in regard to SQLEXPRESS. I have built a small ASP 2.0 web app that runs fine on the local production machine when I go to view a gridview or a detailsview to delete or add records. However, when I try the site out on another machine, it runs fine (logins, etc), however when I go to the data page I get an error stating that the login failed for the ASPNET account.

In SQLEXPRESS, where do I set the permission for the ASPNET account, or how do I go about handling this?

Thanks for the information.

BradJust some other information as I have not yet found an answer to this problem - I am using SQLEXPRESS (as stated in the prior post) and IIS 5.1 for other tables. I can using the login controls just fine. I can add users, etc. I created a new database in SQLEXPRESS and it is the tables to this database that I am having a problem with.

Thanks for the help.

Brad|||Okay, the only Express Manager and grant dbo rights to ASPNET. If there is a better way for this, please let me know because I don't know if it is safe to give those rights to this account.

Brad|||Are remote connections enabled for SQL Express? Can you connect remotely at all? You can check if remote connections are enabled using the Surface Area Configuration tool.

What is the login failure error message in the SQL Express error log?

What is the version of SQL Express that you are using?

Thanks
