I attached a global group to the ISA firewall to grant my users internet access. It worked fine for a while but lately I notice that people who are not member of the global group have internet access as well.
I tested different scenarios:
1. Old global group attached to firewall. Result: everyone has access to internet.
2. New global group attached to firewall. Result: access restricted to member of global group.
3. Local group attached to firewall with Old global group in local group. Access restricted to members of Old global group.
Are there issues with ISA firewalls and global groups? Has active directory been corrupted?
How can I test the integrity of Active Directory?
