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:- Activate and give a new password (one I will remember for step 3 & 7) to the Local Administrator account
- Quit the AD Domain and just put the PC on his own Workgroup
- Restart the PC and log using the Local Administrator account
- Rename all OLD AD Domain users folder
- Delete all Local Adminitrators Group user entry that was related with the Old AD Domain (S1xxxxxxx account)
- Delete all ProfileList Registry Key related with Old AD Domain
- Restart the PC and log again using the Local Administrator account
- Join the new domain and make sure you add the administrator, from the new AD Domain in the local (PC) Administrator group
- Restart the PC and Log as the New AD Domain administrator
- At this point, if you still see the Old share (from the old AD Domain) just disconnect them
- Log Off and Log In again
- If your AD Domain GPO are correctly set (for folder share) you should see them and have normal access
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
