Title: Blocking domain controller?
Post by: Visseroth on March 31, 2017, 12:54:10 AM
So I just swapped out a domain controller, rejoined machines to the domain but following re-joining, randomly Avast starts blocking connections from the workstations to the domain controller which also contains the shares.
It seems to be the firewall blocking the connections as when we disabled the firewall things seemed to get better but I am not seeing a way to add a exception for the local network via the web manager and I don't see in the interface the logs where it tells why it's blocking connections.
I looked through the text logs, some accessible, some not and I didn't see anything in there either that says why the connections to the domain controller are being blocked.
Any help would be appreciated.

Hi Visseroth,

You can find Avast Network Shield Statistic in "Security Tab ; Icon "Network Sheild"

I think you will find what you are looking for in there:

If you moved your machine from an AD (Active Directory) to a new one, you probably have old GPO still in the Workstation.
You need to load the new GPO, from AD, when the machine is connected to the good network (Admin CMD dos command : gpupdate /force
Make sure your machine Network connexion is showing the same name then your AD DNS system.

Thank you  ;D

Any idea how I can set new rules via the web management for the firewall?

Are we talking about "New rules" for Avast or Active Directory GPO ?

Two Completly different things / tasks ...

If I'm refering to your original text (request), you say that you moved some PC from a AD Domain to a new one.

As an IT consultant, every time I do that on a PC with Windows's Operating System, I clean lot of things, before joining the new AD Domain.

Otherwise, you will end up with many problems.

Here a summary of the task I do:

I have applyied these steps to many Windows PC, I have moved from a domain to a new one, and I never had any problem related with avast not allowing me to access the share drive after the AD Domain change.

Hope it will help you
