SSPI: user principle name WCF client

wcf-client sspi

I am trying to access a wcf client. I know people are getting information out of it right now, so I know it works. My problem is I can't seem to get past it. The service is a mutual certific service. I have the appropriate certs in my personal stores on my local machine. Even with that, I get the following exception:

 A call to SSPI failed, see inner exception

Searching deep into the exception and I see this:

Message : The target principal name is incorrect

How can I resolve this? Do I need to impersonate the user the app pool is running under? Do I need to add an Identity\ServicePrincipleName or Identity\UserPrincipleName? Has anyone run into an issue similar to this?

See my answer to a similar problem here: netTCP binding Soap Security Negotiation Failed. This guidance should apply to other bindings, not just TCP.
