Having an issue with WMI on Mulptiple Computers using LanSweeper

We are having an issue communicating to multiple desktops and Servers from our Lansweeper internal Server. LanSweeper is unable to scan the machines using WMI. When we disable the McAfee Firewall its able to communicate. Because WMI uses many ports we don't want to open all the ports for communication. However we can't figure out how to allow Lansweeper through the firewall.

Re: Having an issue with WMI on Mulptiple Computers using LanSweeper

Hi @User70150139 ,

You may try Adaptive Mode to identify ports that are required for Lansweeper. Please follow the steps on an endpoint.

1. Launch McAfee Endpoint Security.

2. Click on drop down next to Update Now & choose Settings.

3. Choose Firewall on the Left & Show Advanced on the top right.

4. Check Enable Adaptive Mode under Tuning Options

5. Click Apply to save changes.

6. Connect to system using Lansweeper Server. [The traffic shouldn't be blocked]

7. Follow Steps 1-3. Click on Rules on the Left.

8. Expand Adaptive and you should see new rules that were created.

9. Take note of the rules and configure it in the Firewall Rule Policy.

* Disable Adaptive Mode when done.

Hi @User70150139 

Please see KB90662 - Troubleshoot an application/network traffic when using ENS Firewall 

Third-party applications that ENS Firewall blocks:
If the ENS Firewall blocks a third-party application from functioning properly, contact the third-party application vendor support team. Request documentation about the specific network traffic that should be allowed through the ENS Firewall. The third-party vendor website might also contain documentation about the network traffic needed by the application. With the documented network traffic requirements, you can create firewall rules to allow the network traffic through the ENS Firewall for the third-party application to function properly.


Also, LanSweeper also has documentation about this.  Please reference the "Ports scanned or used by Lansweeper" Knowledgebase article on the Lansweeper website (restricted from posting the link here).
