We have a simple WCF (on .NET 4.0) Service which uses Windows authentication and same is enabled on the IIS 7 Authentication feature. This works with same settings and same configuration on two servers, but on one of the server comes back with error Security settings for this service require Windows Authentication but it is not enabled for the IIS application that hosts this service. I checked everything possible on web, and tried all the options like disabling other Authentication mechanisms etc. Nothing seems to be working. Could anyone point what can be the issue.
Again identical settigns on two servers is working perfectly on third server it has the issue.

    Did any of the solutions in this thread work?

    From this blog post, it mentioned this KB article.

    If this error is returned and Windows
    Authentication has been enabled in
    IIS, it means there is an issue with
    the supported network authentication
    schemes for the website that the web
    service is installed under. The most
    likely cause is that it is configured
    for NTLM only. We want to specify NTLM
    and Negotiate.
