Hello griffinpet,

Have you configured a FORWARDER in ALL DNS server properties to your ISPs
DNS server?

Best regards

Actually demoting/promoting won't do it, especially if it may be doing the
same thing after you've completed that task. It sounds like more a firewall
block, such as blocking or not allowing UDP 53, or blocking ENDS0. What type
of firewall are in place?

Can you test it with nslookup? Say when you have a problem with a site, such
as that sky.com or any domain, try:

nslookup
> sky.com


Then if that doesn't return a response, try the following command and then
re-run the query:

> set vc
> sky.com


If that works, it tells me the EDNS0 is being blocked.

You an also try prtquery from Microsoft. It will test open ports between
DCs.
