I am having an issue where Avast! is not finding all of our PCs. I have tried searching using both the LAN and AD methods. Anyone have any recommendations? I really do not want to have to add the missing machines in manually.
If these machines are not part of the domain then you need to create an installation file from the console and manually install. If they are on the domain check to make sure the ports are open and/or firewalls disabled and that the network discovery has been enabled.
