Alvin;

I ran into this problem as an anonymous user. A different approach to security may require a different approach.

ASP NET Login Issues for anonymous users

Problem:

Error message – Login failed for user ‘NT AUTHORITY\ANONYMOUS LOGON’.

Reason:

IIS not set correctly

Resolution:

1.	Open IIS
2.	Go to Default Web Site
3.	Right Click on Web Project of interest
4.	Select Properties
5.	Select Directory Security
6.	Go to “Anonymous access and authentication control”
7.	Select “Edit”
8.	Uncheck “Anonymous access”
9.	Select OK
10.	Select Apply
11.	Select OK

Problem:

Error message – Login failed for user ‘(null)’. Reason”: Not associated with a trusted SQL Server connection.

Reason:

IIS and/or Web.config may not be set correctly

Resolution:

See above to set IIS.

In the Web.config file add the following line after the <system.web> tag and before the </system.web> end tag

<identity impersonate = "true"/>
