Reproduce Issue: The http request was forbidden with client authentication scheme 'anonymous'

Question

I would like to re-produce the wcf issue : The http request was forbidden with client authentication scheme 'anonymous'

We are using wcf service in our product and we have hosted the wcf service as Windows Service (Self-Host service) and this wcf service is being consumed by a small windows client app.

Things are working fine in our environment. But, one of our customer reported that they are receiving the error "The http request was forbidden with client authentication scheme 'anonymous'" while they connect the client app from remote client machine.

Here, my question is, can anyone help me to re-generate this issue in our environment, so that we can give perfect fix.

I found this in the msdn forum, I hope this helps you:

Since you have specified Security Mode= none for WsHttpBinding, when it make request to WCF service , service will try to authenticate client using Aninymous credentials, but in case of different domains this will not work, so try to use X509 certitifates.

So try to establish a connection between two different domains.
