Vista - The pipe name could not be obtained - when using ASP.NET Impersona

I have a web application written in VS2008, trying to use a WCF service
running on a console. The service is running as me - the person logged in,
while the web application is impersonating an administrator user on the
windows 2003 server. I notice I get the below error whenever trying to make
the WCF call using impersonation. It works if I make it false.
