WCF - Getting the "The authentication schemes configured on the host ('Anonymous') ....." error

Question

"The authentication schemes configured on the host ('Anonymous') do not allow those configured on the binding 'BasicHttpBinding' ('Ntlm'). "

I am brand new to WCF and services in general. I have turned on the basic, windows & digest auth modes in my iis express.

One thing I just noticed in my iis express config file, I had turned on basic auth in the "turn of windows stuff" in the task manager then rebooted, but I just opened the applicationhost.config file on my machine and saw this:

        <authentication>
            <anonymousAuthentication enabled="true" userName="" />
            <basicAuthentication enabled="false" />

shouldn't that basicAuthentication read as true?

I was given this existing project to make some changes to, but I cant even get it to run on my machine, so I'm assuming something is up with my local iis express settings.

This project has 3 services in it. Here is a partial of the webConfig:

    <bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBinding_IDataMaintenanceService" maxBufferSize="2147483647" maxReceivedMessageSize ="2147483647" maxBufferPoolSize="2147483647" >
          <readerQuotas maxDepth="2147483647"
          maxArrayLength="2147483647" maxBytesPerRead="2147483647"
          maxNameTableCharCount="2147483647" maxStringContentLength="2147483647"/>
          <security mode="TransportCredentialOnly" >
            <transport clientCredentialType="Ntlm"/>
          </security>
        </binding>

        <binding name="BasicHttpBinding_IYearEndProcessingService" maxBufferSize="2147483647" maxReceivedMessageSize ="2147483647" maxBufferPoolSize="2147483647" >
          <readerQuotas maxDepth="2147483647"
          maxArrayLength="2147483647" maxBytesPerRead="2147483647"
          maxNameTableCharCount="2147483647" maxStringContentLength="2147483647"/>
          <security mode="TransportCredentialOnly" >
            <transport clientCredentialType="Ntlm"/>
          </security>
        </binding>

Turns out that even though I had enabled the various auth types in the "Turn on windows features...", they didn't actually turn on, so I had to modify the iis config file manually. I found the config file in the iisExpress folder in My Documents.
