Make sure that no firewalls are blocking traffic from the Nexpose Scan Engine to port 135, either 139 or 445 (see note), and a random high port for WMI on the Windows endpoint. You can set the random high port range for WMI using WMI Group Policy Object (GPO) settings. 3- 135 port must be open on the remote server And an ephemeral port range of ports 1024 to 65535 are to be left open. WMI first uses port 135 to negotiate, then DCOM selects a random port between 1024 and 65535. 4- If you have a domain\user_name on the Windows server you need also to use the same for the auto discovery job.

An alternative to telnet in checking ports is Network Utility. In order to check ports on a Mac, follow the plan below: Open "Network Utility" > Click "Port Scan" > Indicate the hostname and ports to scan the remote host e.g. myserver.com from 995 to 995 > Check the output Acting on the results obtained from the Telnet test Nov 13, 2019 · # # # Script queries port 135 to get the listening ephemeral ports from the remote server # and verifies that they are reachable. # # # Usage: RPCCheck -Server YourServerNameHere # # # Note: The script relies on portqry.exe (from Sysinternals) to get port 135 output.

Make sure that no firewalls are blocking traffic from the Nexpose Scan Engine to port 135, either 139 or 445 (see note), and a random high port for WMI on the Windows endpoint. You can set the random high port range for WMI using WMI Group Policy Object (GPO) settings.

This limits the range of ports you need to open on the Windows Firewall. If you do not assign a static port, you must create a firewall rule permitting the entire dynamic range of ports: On the Archive server, open the Windows Firewall application from the Control Panel. Click Advanced Settings in the left pane. At any one time, there’s a whole bunch of information being sent between your Windows 10 PC and the endless void of the Internet. This is done using a process whereby network-dependent processes seek out free TCP and UDP ‘ports’ through which they communicate with the Internet.
