The service does not know who you are. In your client app.config you should have an entry something like this: 
&nbsp; &nbsp; &nbsp; &nbsp; 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 
 
&nbsp;can be your computer name if you are just running on your home machine. Normally if you tell VS2008 that you are creating a WCF service it will put this in for you. Or you can put a certificate name or servicePrincipalName in there. 
 
It also could be on your service do you have this in your web.config? 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 
then for now you should comment it out.

There's aint any web.config and i got this app.config only.. 
 
but so how i try to change value to mycompany@company.com from 
 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 
 
it doesnt like it.. 
 
From the web, i found some users adjust Certificate Authority and restart the service, they worked over there.
