quick Google results, so don't quote me on this https://support.microsoft.com/en-us/help/832017/service-overview-and-network-port-requirements-for-windows
other pages (old, window server 2008-ish) says the number socket ports is 65535-49152=16383 but the range can be expanded with "netsh" e.g netsh int ipv4 set dynamicport tcp start=1025 num=64511 https://support.microsoft.com/en-gb/help/929851/the-default-dynamic-port-range-for-tcp-ip-has-changed-in-windows-vista see also https://serverfault.com/questions/648424/windows-server-2012-r2-runs-out-of-ephemeral-ports-though-it-shouldnt This feels like some kind of TCP overload to me. ********************************************************************** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **********************************************************************
