I have a WCF service that works fine on the LAN but when trying to access it from outside the service reference fails.
My WCF service is hosted on a win2k3 box that is using a static IP no domain.
This is what worked for me. In config file
< serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
< / system.serviceModel >
If it is set to false, I was getting that crazy computername substitution.
multipleSiteBindingsEnabled="true"
seems to be all that I have to do for this to work as it should.
