# Error: The request failed with HTTP status 404: Not Found

Every time I use the Blueprint Server Configuration utility, I get an error when testing the Web Server. Errors: 1. The request failed with HTTP status 404: Not Found Or 2. Web server responds with unrecognized html

This is related to a permissions issue:

1. Open IIS
2. Click Web Server Extensions
3. Make sure [Asp.net](http://asp.net/) 1.1.4322 is set to Allowed

**Note:** If the client is running version two of [ASP.NET](http://asp.net/) this is not supported with 3.1 or 3.2. Have the client install 1.1.4322 and make sure it is set to Allowed in the Web Server Extensions. Blueprint will look for and use version 1.1.4322.
