ESET 6 Network items 'Non-Functional'

Recommended Posts

We are a small business with ~40 devices protected by ESET, over the last couple of weeks 3 devices have now shown everything under the Setup > Network tab as 'Non-Functional' despite being enabled

 

This has happened to 2 desktops running Windows 10 and a laptop running Windows 8.1, using versions 6.1.2227.0 & 6.2.2021.0

 

Uninstall and reinstall did not fix the issue, nor does resetting to Default settings. Uninstalling to update the Windows 10 machine left the PC unable to use any of the network cards so a System Restore was the only option, which has fixed the error on that PC for now.

 

The only interesting thing I've noticed is the UAC has stopped prompting for changing Firewall mode on these machines until the Default Settings are restored.

All looks in order.

That's odd. If you close gui by holding Shift and clicking X and then start gui from the Start menu, is personal firewall still shown non-functional in gui?

The Windows 8 laptop was showing errors from those commands, updating to 6.2.2021.0 seems to have resolved this.

 

The Windows 10 machine still doesn't work, same after a shift click x, see attached.

 

Is there a reason a network card would stop working after uninstalling ESET under Windows 10? I'd like to uninstall and update the software on this machine but the other machines network connections disappeared (adapters were still there) causing a lot of panic until a System Restore.

Hello, if you uninstalled using our standalone Uninstaller tool, there is currently a known issue on Windows 10 which fits your description. A newer version of the tool is in the works.
In the meantime, the steps to take can be found here: hxxp://support.eset.com/kb2289/#Windows10 (As the issue is already present, focus on step 2 "Uninstall the Epfw NDIS LightWeight Filter")
