Since August, this has been happening to me each time I install new Windows Updates. I have to go and add the DNS server IP address under the ZA Firewall Zones tab and it goes away. (Of course, now there are 2 DNS server entries.)

Oldsod put some great instructions here in the Forum.... somewhere. I've been looking for them, but, haven't been able to find them again. I can tell you that that Port 135 is your own computer. (Learned that from Oldsod, as well.)

Maybe someone else knows where it is and can give you the link. I'll keep looking.

Note: I know NOTHING about how to do any of this stuff, so, don't do anything until someone comes up with a link!!
