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.
