I have a TCP (GPRS) windows service running on a Windows 2008 Server R2 on a virtual machine. When the service is started around 1500-1980 TCP connections are made by client devices on a port. Once this limit is reached other connections are refused.
I have added the registry entry MaxUserPort and set it to maximum without any increase. I have set the following keys as well:
I think it is fine with current settings in order to restrict the max number of the connections on server.
But may I know the further concern about why we have to do that ? avoid getting folding attack ?
