Well there is a problem getting data across your network (sockets).

I'm not 100% sure what is causing this but the first thing I would check is permissions.

Make sure that the users are permitted to use the resources necessary to run the application across the network like this.

The reason I suspect permissions is because, in your first post, you are having problems receiving data in the ProcessAuthentication method...

Sorry I can't be much more help.
