Server Security v12.11 on Domain Controller block DNS (Yahoo)

I have Server 2008R2 domain controller with DNS and F-secure Server Security v12.11. Web page login.Yahoo ( is blocked with error DNS not found.

I added a path "C:\Windows\System32\dns" in excluded object but it didn't help.

When i disable FSMA on domain controller, clients can access to Yahoo mail.

Any advice?
