SX, unfortunately
Got an issue that I think is DNS that shows sometimes and is mildly annoying.

Environment is Server 2012 R2 with either RDP or 8.1 clients.

I've got two repeatable issues, there are other intermittent ones.

Repeatable 1: When I go to Manage Add-ons/Tracking Protection/Get a Tracking protection list online without fail I get a This page can't be displayed error. Same with find search providers.

Repeatable 2: If I type in the address https://www.halifax-online.com/ in the address bar I get the same error. If I type google in the address bar, google comes up. Searching for Halifax-online and clicking on the link works fine. Search from the address bar is enabled.

Any ideas? :)

Thanks
 
Could the additional issues you are facing with halifax-online.com be somehow related to the fact this site is a bank site that is susceptible to phishing attacks. Therefore something on your computer is recognising that?
 
to see if its a DNS issue change the DNS settings to googles free ones.

in your IP settings put in the following

preferred DNS server - 8.8.8.8
Alternate DNS server - 8.8.4.4

if it works then you know that is the issue
 
Changing to Google does work - so I guess that just confirms it's a DNS issue?

I already have Google in the forwarders list on the DNS server, and most sites work, so not sure where to go from here? :(

thanks :)
 
you could try to flush the DNS cache.

open up command prompt as a admin and pit this in

ipconfig /flushdns

does it work on another PC or do you not have one to hand to try it on?
 
Tried that, and also scavenging stale records etc. on the server :(

It doesn't work on any of the machines connected to the domain :(
 
I had a very similar issue to this, it was related to my ISP basically we changed ISP and when the line went live we could access some sites and not others.

After much investigation it turned out to be a routing issue upstream at our provider.

Any major changes on your site prior to this issue?
 
If it was the ISP wouldn't it still not work when I bypassed the DNS servers?

I've not tried removing a machine from the domain - what would I look for when I did as even if it's not a member, it would still pick up the same DNS servers?

I did find something yesterday, I had to restart the secondary DNS server, and during that time DNS wasn't available at all - so it looks like the primary is doing naff all...
 
Still struggling with this :(

BPA shows no errors for DNS. There's quite a few forwarders on the list - I've been gradually adding them over time to see if the problem goes away!

Originally it was just the google ones, but have added the plusnet, dyndns and a few others with no luck :(

I have found something though - some machines it works on, some it doesn't.

Those that it doesn't work on, when I run nslookup gives the UnKnown error.

That confuses me though as the "fix" is to re-do the A and PTR records - but as it works on some machines that means they're ok?
