Why do I get a 403 error when calling a WCF Webservice?

I'm really posting this question so that others searching for the answer can find it.

Scenario: WCF Service: Has worked fine at some point but currently is returning 403 errors. The web.config looks fine as far as I can tell. This machine has set the web.config to disable transport and message security and is using BasicHTTPBinding.

When I call it with my client generated from the Service Reference in Visual Studio, I get a 403 error. The error indicates there is some problem with the authentication, but as far as I can tell there is no such problem.

To solve this problem, I used Fiddler to get the actual error code - in this case, a 403.1. This indicated that the executable for the service couldn't be run.

The actual problem ended up being that the ASP.NET version was set to 1.1, not 2.0+. So setting that to 2.0 resolved the 403 permission error.

Http 403 error is "Forbidden". There is something that is blocking access.

In cases where it worked at one point and then stopped, it is often a windows update that has tightend up the security.

  • Where is your WCF service installed?
  • What are the ACL's on these files?
  • What is the security context of your service? (Which account will be used to access the files)
  • Does that user have access to the files?
