The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Using Windows Authentication to SQL Server 2005 For WebParts Credentialing

Asked by stuengelman in Programming for ASP.NET, .NET Framework 3.x versions, SQL Server 2005

Tags: WebParts Windows Authentication SQL Server 2005 ASP.NET VB

Hello,

I'm trying to implement webparts in my ASP.NET web application (VB) using Visual Studio 2008.  I am attempting to utilize Windows based authentication in order to implement personalization (rememberance of webpart control positions accross ASP.NET sessions at the user level).  The personalization database is housed in SQL Server 2005.

The error I receive when trying to navigate to the applicable page with webparts is:

"Cannot open database "OfficeBookDB" requested by the login. The login failed.
Login failed for user 'NT AUTHORITY\NETWORK SERVICE'."

At the SQL Server level, I've ensured that Windows authentication is turned on, and I've granted login access to the 'NT AUTHORITY\NETWORK SERVICE' account to the applicable database.  I've also run aspnet_regsql.exe to create the personalization provider within the database.

At the project level, I've made several additions to my web.config file (these are shown in the code snippet section):

(1) Added code for the connection string.
(2) Set Authentication Mode to Windows.
(3) Provided Web Parts Personalization section.
(4) Enabled identity impersonation.

Thanks, Stu Engelman

         </providers>
    </personalization>
</webParts>
