Everybody knows the problem, when you try to authenticate on an IIS site under Windows Server 2008 R2 like SQL Reporting, etc.  then the most of the time you could get an error. That means you are prompting all the time to enter your credentials.

Error message would be.

You do not have permission to view this directory or page.


A simple solution would fix that common problem.

Goto IIS, then to the Default Web Site or whereever your site is hosted. Then click Authentication and go to Windows Authentication and to Providers. Here you have to add or if you have it already just move NTLM to the TOP.



Thats it. Hope that helps. Smiley mit geöffnetem Mund
