I currently have a .NET service that listens on a single port over a TCP protocol. Here's the way it works: Our clients connect and transmit their data for periods at a time. Is there a limit on the # of connections on Windows Server 2008? I haven't hit any yet but I'm worried since our company is up to 50 clients. Our plan is to add a hundred more over the next few months so I need to know if this will become a problem. Thanks!
