WCF Access Denied
===

I have a PC with a WCF service localhosted, I can add a reference to the service in a C# program.  However when I run the program, I get an Access Denied error.  I get no other information apart from Access Denied.  

Does anyone have any suggestions on what to do.  I have another machine which looks the same set up but am able to connect to the localhosted version on the same machine.  I've looked at other questions already posted but nothing seems correct.
