I have a couple of pc's that are stating and giving an error on Symantec Client that the Firewall is Malfunctioning. Does anybody know how to fix this issue. Any help would be awesome.

 

Thanks,

Joshua

 

What version is this for?

Did you try rebooting the machine or running a repair on the client?

Its for version 12.1 and I ran a repair, uninstalled ntp and then reinstalled to other articles I read. a reboot didnt fix the issue. Thanks for the response Brian81

Did you try running cleanwipe and reinstalling fresh?

Did this just start or been going for some time?

Yeah I tried that and for some reason even a cleanwipe doesnt take care of it. Its been going on for at 3 weeks to a month, somewhere around there.

hello,

On SEP 12.1 RU1 MP1 this issue is fixed.

A fix for this issue has been released in the 12.1 RU1 MP1 and 11.0 RU7 MP2 versions of the Symantec Endpoint Protection product.

 

In case it is not immediately possible to install the latest available SEP release, the steps below outline a separate workaround:

1) Uninstall SEP client from the Win 7 Machine
2) Take back up of the registry
3) Delete the following keys

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\eventlog\System\Teefer3
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\services\eventlog\System\Teefer3
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\services\Teefer3
HKLM\SYSTEM\CurrentControlSet\Services\Teefer3

4) Reboot the machine
5) Reinstall SEP client.

Hi

Please upgrade the SEP clients to SEP 12.1 RU1 MP1

Regards

 

Hi,

If possible can you test with fresh install of SEP client?

 

Hi,

When you run clean wipe is it completely uninstall your sep client?

has it rebooted twice?

If not run the cleanwipe again and reinstall the client. 

hi,

This issue are fixed in sepm 12.1RU1 MP1 you can upgrade your sepm server.

Try to install Fresh sep client

I have ran the cleanwipe and did two reboots and still having the same issue. Just got informed by our team here with my company to just uninstall the ntp firewall protection and then leave it off and that should fix the issue. So going to try that to see if it works.

Thanks for everyone's input. Will reach out if fixed.

Hello,

Could you try visiting the Device Manager > View > Show hidden devices > Check if you have any yellow exclamation OR Red X under "Network Adapters" Or "Non-Plug and Play Drivers"?

Also try removing the  Network Threat Protection (NTP) component, then reboot the machine and install it again.

1. Windows Control Panel > Add or Remove Programs > Symantec Endpoint Protection > Change > Modify >  Network Threat Protection > Entire feature will be unavailable.
2. Reboot
3. Windows Control Panel > Add or Remove Programs > Symantec Endpoint Protection > Change > Modify >  Network Threat Protection > Entire feature will be installed on local hard drive.
4. Reboot

OR 

TRY installing the SEP 12.1 RU1 and check if that resolves the issue.

If the issue still persists, Try Running the Cleanwipe version 12.1 (available with Technical Support)

Hi,

Thanks for the update.

Make sure you have enabled Windows firewall, because either Symantec or Windows firewall should be enabled.

 

Thanks Chetan, I made sure that the windows firewall was on. And everything looks good now.
