Hello,

I have frequently svchost.exe trying to create a connexion from the DNS server to my computer. Usually, I block this communication manually and I don’t have special problem.

In order to understand, somebody can explain :
Why does this type of communication happen ? What is the goal ?
Do I have to Allow this type of communication ?

Thank you

Fasty

Svchost.exe should be set for ‘Outgoing Only’.
