Endpoint Protection

We have the same issue on our new win 10 machines installed with network install (MS Deployment toolkit)

we know the workaround is to uninstall SEP, install the teefer driver on the nic, and reinstall symantec

We also noticed that when we install the teefer driver before SEP it works fine, so in our deployment script I want to install the teefer driver before sep gets installed but cannot find a way to script installation of the driver...

anyone know a script that will do that?

Thanks Dear, It worked for me.

Manuall steps to bind teefer driver to NIC

1. Open properties of NIC adapter.

2. Click Install and select 'Service' and then click 'Add'

3. Click 'Have Disk' and browse to "<Symantec install path>\12.x.xxxx.xxxx.xxx\Bin"

4. Based on the OS, select 'teefer.inf' file from followng folder and install.

TeeferVista (winVista & win7)

TeeferWin8 (Win8 and above)

TeeferXP (winXP & win2003)

5. Reboot machine and check.

• Uninstall SEP if you have it installed


• Reinstall as Administrator.
  
  
  
  • Right Click - Run As Administrator.
  
  
  
  


• Fixed the issue for us.

THANK YOU ELANGOVAN!!!

Using Win10 with Symantec v14.  Have noticed this started with v12, in 2013.

I'm thanking Elangovan in mid 2017, yet still no fix from either Symantec or Microsoft...

After ripping my hair out, I am just glad I came across this...

Check this thread, https://www.symantec.com/connect/forums/firewall-disabled-firewall-malfunctioning

If Step 1 of the instructions is "Open properties of NIC adapter," you probably should tell someone how to do that.

Thanks !!!!!!!!!!!!!!! Elangovan worked great.

HOLY CRAP!!!!  I tried Elangovan instructions and it WORK!!!!   Thanks a lot.

In my case faced this problem on Win8, due to the TEST CERTIFICATE not installed in proper store. In that case SEP installation will succeed but 'Firewall driver is not loaded'.

But this solution resolves when SEP has 'Firewall driver is not loaded' issue.

Hm.. so what is the work around then ?

Had this problem and found the solution, there's a limit on network filters per adapter.

My Windows 7 laptop also suffer this same problem with 12.1.2015 RU2

nevermind.....after much toil, i was able to uninstall SEP which automatically fixed the network issue and reinstalling fixed the original issue (i.e. firewall driver not loaded message).

tried that and it broke my network card i no longer have network connectivity....i get limited access message. reinstalling network cards have failed and so has uninstalling and reinstalling.

can you please advise me?

running windows 7 64 bit symatec 12.1.3001.165

Thanks for posting.

Any info on the root cause of why this happens?
