So here is a theory if a client asks a query and bind goes out for that
query and the reply is delayed but you get the answer then for what ever
reason the reply to the client from bind is delayed more! So the quicker
the answer the quicker the answer to the client.
Why? I have no idea?

and this from dig maybe a routing iusse why it take so long for me?
C:\Program Files\ISC BIND 9\bin>dig @213.227.191.1

This is the thing the setup works for many site fast just this
Teamviewer and their DNS servers are a problem and bind does reply to
192.168.53.19 all be it 26 seconds later! but Teamviewer trys over and
over then it connects yet the for the WAN side took under 4 seconds to
get the answer WAN
Have you checked the routeing table on this server?
Without any other evidence, this looks to me like packets are going places
you aren't expecting.
In the first screenshot the query goes to 213.227.191.1 and apparently a
response doesn't come back until 4s later. When I try it using dig I get an
This might show the problem even more on two interfaces WAN side and LAN
you can see 192.168.53.19 ask for routerpool8 #60 then bind goes out #62
gets a answer # 75 and no reply back to 192.168.53.19

On starting Teamviewer it can say no connection when bind does the
lookup with this delay it cause bind to not reply LAN side sometimes
which causes the app to fail yet with a bind on Ubuntu there is no problem.

I'm just using bind to do my DNS look ups with no forwarders thats all
Teamviewer app uses DNS to find its servers from what I can tell it can
take over 4000ms to get a answer.
The following seems to help in bind
resolver-retry-interval 5000;
I think if I can then find a setting in windows
Hi there.
Can you send some information, for those unfamiliar with what you're trying
to do?
- Full BIND config
- IP addresses of relevant things, like interfaces of the servers on which
you are running BIND and of Teamviewer.
- What does Teamviewer need from DNS? What kinds of queries is it
Now its not working fast again! I don't know now must be Teamviewer DNS
delaying replies causing windows bind to fail in some way.

So more tests and the problem has come back but I think I know why
thinking internet sharing was the problem I found a way to disable it
because it bind shared access for port 53 on 0.0.0.0 so that the problem
I think now after testing with it on.
For any interested MS has made it really hard
I'm by no means an expert in DNS or how it fully works so I can't be of
any more help about this problem then I already have. But it seems
Teamviewer have rebooted their DNS servers and now windows bind allows
the Teamviewer to load faster

Hey,
BIND 9.16 is in security-and-critical-only mode, so this won’t get fixed in any
case.
However, your message is incomprehensible. If you want to get anything fixed,
we will need more clarity in the report - describe your setup (clients,
recursive servers, authoritative servers) and
I don't know if this will be fixed before EOL for windows bind but here
is the problem
Teamviewer (and maybe other sites too) when you do the recursion when no
answer under 1000ms it tries again which is trigged by client windows
(not the one running bind) which also tries again for a answer
