I have a WCF service hosted as a Windows Service. The server hosting it is running IIS6. Every so often clients report a 503 Service Unavailable error.

Hi, I have an application which will use WCF to serve up various chunks of data to clients. However, due to the size of some of the sets of data that will be returned (and that's because the client app needs to show a large number of objects in a list, not because I've just been lazy in the design) I'm hitting the message size limits. ...

Got a simple WCF demo app that has two console projects--host and client. Both are running on my machine (win 7 box). I'm using the netTcpBinding, which uses windows authentication.
