Network issues with SEP 11.0.6200

Created: 06 Jul 2012 • Updated: 06 Jul 2012 | 9 comments

Hi,

We have SEP ver 11.0.6220 installed in our server and it's being pushed to all clients. From the past three days, we have been facing issues with both LAN and WiFi showing exclamation marks in device management. Uninstalling SEP made WiFi work. This is for a brand new laptop. Need help urgently as the issue is spreading slowly and surely to all laptops. Any help would be appreciated!

Which all are the SEP features installed in the client?

 

Try by uninstalling NTP.

* NTP having the firewall component and  teefer2.sys is the driver file for the firewall component

* Teefer driver is upgraded on 11.0.7 for the network based issues with SEP firewall

* Windows 7 SP1 and above and Windows 2008 servers SP1 and above is compatible only with SEP 11.0.7 and SEP 12.1

@Mohan Babu - "Symptom: Installing SEP with NTP causes the client to lose all communications with SEPM. All other network traffic remains unaffected."

In this case, no network is working as all devices are showing as corrupt and rollback of drivers, updation of LAN drivers manually also is not working. Please help.

Hi,

Possibility of driver conflict.

If it's happening with brand new laptops you should test with latest SEP version.
