Wcf – Why can’t I connect to a WCF service with net.tcp but i can with http


I have a WCF service running on the IIS with a ServiceHostFactory. It's running fine with the WSHttpBinding but because of the speed and everything being on the same network (no firewalls) i want to speed up things a bit using the NetTcpBinding instead.

When i try to do that i get this error:

Could not connect to net.tcp://zzz.xxx.yyy/MyService.svc. The connection attempt lasted for a time span of 00:00:01.0464395. TCP error code 10061: No connection could be made because the target machine actively refused it x.x.x.x:808.

I'm using SecurityMode.None just to make sure that is not screwing me also i tried either of these on two different tries:

binding.Security.Message.ClientCredentialType = MessageCredentialType.None;
binding.Security.Message.ClientCredentialType = TcpClientCredentialType.Windows;,

Also i should point out, that i'm pulling quite a lof of data from one of the service calls, so i also put these (both on the http and the tcp attempts – setting maxMessageSize to 1000000)

binding.MaxReceivedMessageSize = maxMessageSize;
binding.ReaderQuotas.MaxArrayLength = maxMessageSize;

It should be pretty easy getting it to work, so what am I missing?

UPDATE: I added the TCP port 808 to the website identity and tried again. Now i get this error:

You have tried to create a channel to a service that does not support .Net Framing. It is possible that you are encountering an HTTP endpoint.

If you are using Vista, then ensure the WAS and Net.Tcp Listener Adapter Services are running.
