Symantec Endpoint Protection

Hello we have Symantec Endpoint Protection 12.1 MP1 installed on Windows7 en Windows XP workstations. When Symantec processes an definition update on these client worksations all network connections at the client are disconnected for one second. What is causing this behaviour? We also use Symantec 10.1.8 at some other workstations and they don't have this problem. I hope someone can help.

Sounds like you have an issue with the NTP module settings. I would open a support case with Symantec though as this is not a default behavior. I would also look at your firewall settings, something in there might be misconfigured.
Did you see anything in the EventLogs? Did you notice the network icon saying disconnected and then connected after 1 second?

Thanks for your comments.
We are trying to make a call with Symantec but have some registration issues.

I've had a Windows 7 desktop with de Windows 7 Firewall disable still this disconnection then also disabled de Symantec Firewall but stil this strange diconnection for a split second.

I have not noticed the icon changed from disconnected to connected. The EventLogs seems normal.
Did these PCs have Symantec Antivirus 10 installed prior to the install of SEP 12.1? If I can recall correctly, we had similar issues when migrating.
Yes these pc's had Symantec Antivirus 10 installed prior to SEP12.1. Dit you solved it?
