Hello,
I am receiving an error when I try to connect to a WCF Service hosted in IIS 7 on a service inside our network from a Desktop Client.  The service appears when you enter the http://domain.com/servicename.svc in a browser window, but I cannot seem to get the client to connect to it from a different box.  

This is the error message:
Client is unable to finish the security negotiation within the configured timeout (00:00:00).  The current negotiation leg is 1 (00:00:00).

I used this as a base, but in their example they are not hosting in IIS and both the client and host are on the same box.: http://www.eggheadcafe.com/tutorials/aspnet/b5ada8df-58c5-492f-b368-457b3a4f137c/notify-client-application.aspx
