title: What is the theoretical maximum number of open TCP connections allowed on a Windows server
body: <p>On my Windows server I have a port open listening to incoming TCP connections from multiple clients. Is there a limit to the number of unique clients that can concurrently establish a socket connection on that opened port on my Windows server?  One of the threads <a href="https://stackoverflow.com/questions/2332741/what-is-the-theoretical-maximum-number-of-open-tcp-connections-that-a-modern-lin">What is the theoretical maximum number of open TCP connections that a modern Linux box can have</a> talks about number of socket connections being limited by the allowed file descriptors on Unix platforms.  Is there such a limitation on the latest available Windows servers? If so how to go about changing that limit?</p>
