Avast Internet Security version 17.4.2294 (release date 5/3/2017)
We have a small Windows network, single subnet, Windows 2012r2 AD server. This network/server has been running for the last 2 years.
We have used Avast Internet Security on our desktops for 3+ years.
As of about 2 months ago:
Randomly, server will "disappear". No ping, no windows browsing, nothing.
Pinging all other devices works fine. Server can ping everyone just fine except affected desktops.
Disabling Avast is the only way to bring it back.
I have removed and re-installed Avast. Version is current as of 10 minutes ago.
WTH else can I do? Avast firewall CLEARLY does not like our windows server.
