GPO: Cannot Edit Setting In Windows Firewall With Advanced Security

less than 1 minute read

Description:

I wish I could find a screenshot of this but what happens is: You want to modify a GPO that is pushing firewall rules and you go to change them and you get a red box saying something about ‘cannot connect to the domain’ only in that section of the GPO, other settings work fine.

To Resolve:

1a. The fix is to find your PDC Emulator

Get-ADDomain | Select PDCEmulator
  1. RDP to that DC and then try editing the rules, it will then work!
