In order for Lansweeper to scan your vCenter servers, you need to ensure that TCP port 443 is open on the vCenter server and that the server's HTTPS title contains the text "ID_VC_Welcome". If you encounter issues while scanning your vCenter servers, you can go through the troubleshooting steps below to resolve the problem.
VMware vCenter scanning troubleshooting
If you encounter issues while scanning your VMware vCenter servers, do the following:
- Make sure there is no general scanning issue by going through the steps in this knowledge base article. After double-checking all the items in the aforementioned article, rescan your vCenter server.
- Use the Lansweeper Devicetester to make sure that the vCenter server meets the vCenter scanning requirements. Check that TCP port 443 is open on the vCenter server and that the HTTPS title contains the text "ID_VC_Welcome".
- Make sure that the machine is a vCenter Server Appliance (vCSA) and that TCP ports 135, 139 and 445 are closed on the vCenter server.Scanning a vCenter Server environment installed as software on a Windows computer is not supported. If Lansweeper determines a machine to be a Windows computer, if it finds TCP port 135 to be open, vCenter scanning is skipped.
- Check connectivity from your Lansweeper scanning server to the vCenter server using a Telnet connection. Open an administrative Command Prompt on the Lansweeper scanning server. Telnet to the IP address of the vCenter server in question on port 443 and check if a connection can be made. See example command below.telnet 192.168.2.119 443
