Opening a Port - v9 SR4

Anonymous — Mon, 26 Jan 2026 18:19:17 GMT

From the v9 SR4 Release Notes:

Windows Server 2008 has port 4747 turned off by default. QVS will then fall back to HTTP
tunneling which may have an adverse effect on performance.

How do I do this on my server? Do I create an Inbound Rule that just allows TCP for port 4747? How do I check if it's working (NOT tunneling)?

You can verify communication on port 4747 by using Telnet

Open a cmd.exe on a klient machine and write

telnet <serverip> 4747

You should get at blank window if the port is open.

Brian,

You should open 4747 both inbound and outbound on the server and client.
