He looses once a day internet connection, although the network icon within the status bar shows a connection. First he was able to fix that issue with a re-boot. Later on he was forced to reset the network. He has changed the network card without an improvement. Searching the web brought me to <a href=\"https:\/\/social.technet.microsoft.com\/Forums\/en-US\/69449ce9-ea58-48ec-b675-c55480ba4bbb\/windows-server-2012-and-tcpip-maxuserport?forum=winserverPN\" target=\"_blank\" rel=\"noopener\">this English<\/a> Technet-forum discussion, where the same issue has been observed with Windows Server 2012:<\/p>\n<blockquote>\n<p>Sometimes the server becomes inaccessible no network access anymore with 2 events:  <\/p>\n<p>ID 4227:  <\/p>\n<p>TCP\/IP failed to establish an outgoing connection because the selected local endpoint was recently used to connect to the same remote endpoint. This error typically occurs when outgoing connections are opened and closed at a high rate, causing all available local ports to be used and forcing TCP\/IP to reuse a local port for an outgoing connection. To minimize the risk of data corruption, the TCP\/IP standard requires a minimum time period to elapse between successive connections from a given local endpoint to a given remote endpoint.  <\/p>\n<p>ID 4231:  <\/p>\n<p>A request to allocate an ephemeral port number from the global TCP port space has failed due to all such ports being in use.  <\/p>\n<p>Is there any way to resolve this? In previous version of windows server there was some registry entry for the tcpip parameters but they don't seem to exists anymore.<\/p>\n<\/blockquote>\n<p>Someone suggested the following workaround to avoid the exhausted TCP\/IP connections. <\/p>\n<p>1. Launch registry editor <em>regedit.exe <\/em>via <em>Run as administrator<\/em>. <\/p>\n<p>2. Change the following registry entries.<\/p>\n<p>Navigate to branch:<\/p>\n<p>HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters<\/p>\n<p>and set the value <em>TcpTimedWaitDelay<\/em> to 30 seconds. Then navigate to: <\/p>\n<p>HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters<\/p>\n<p>and set <em>MaxUserPorts <\/em>to 65,500. If the subkeys or the values are msising, just create them within registry editor.
