Hello,
Anyone know which port number used by WBEMTEST? I do WBEMTEST to one server but failed and there are firewall behind the server. Security team ask me which port is used so they can open the ports.

Hello,
WBEMTEST is a utility used to test Windows Management Instrumentation (WMI) connectivity. WMI typically uses DCOM (Distributed Component Object Model) for communication, and DCOM operates over port 135 for initial communication.

It's only need single TCP port 135? I can telnet to remote server with TCP port 135 but the WBEMTEST still failed.
Hello,
DCOM assigns a dynamic port for subsequent communications after the initial connection. These ports are usually in the range 1024-65535. Therefore, you may need to ensure that your firewall allows communication on these dynamic ports.
