IIRC, the DNS servers are provided for you when you get an IP from the DHCP server so entering a different proxy will do nothing.

The only reliable method to bypass the NTL DNS is to run your own DNS server which directly queries the root servers and specify that server in your network settings for DNS, instead of "automatically assigned".

I did exactly that. When it got really bad, I switched to a friend's DNS in Europe and viola! lightning fast connection to the World Wide Web.

It has saved my connection now more times than I can remember.

My Network Places-->Properties-->Local AreaConnection-->Properties-->
TCP/IP-->
and tick "use the following DNS server addresses" and put the DNS in there.

The trouble is that slow browsing can be caused by several things.

1. Network latency/lag
2. Poor xparent web cache (NEVER)
3. Slow DNS servers

When I get slow browsing problems (about 20 a week) I change my dns to bt's dns servers and use a proxy server that is out of the area. This allways fixes the problem. I now leave my proxy settings to an out of area proxy as its not worth changing it back.

Latency/lag can be down to an oversubscribed UBR...

I have had problems for a while now which I am sure are DNS related.
My AV software from Command is set to "AutoUpdate" and until recently it worked OK, updating deffiles and patches seamlessly in the background. I also receive automatic email notification of any updates, and for the past month or so the deffiles have not auto updated until 3 or 4 days after they have been posted on the Command website. If I use the "Update Now" feature it times out. If I go direct to the web site and try to download the deffiles updates manually I get a DNS error.
However if I use my Zen dial up account I can access the deffiles perfectly.

So ( numpty head on) how do I configure my browser to use the Zen DNS servers with my Ntl BB connection, bearing in mind that as far as I am aware the proxies are still turned off in this area.

PS I have already added the Zen DNS servers to ZA Pro.

Thanks for those numbers th'eng.. poked around in network settings and found out where to stick them.

Made no difference at first, then I hit Ctr+f5 and the deffiles updated instantly.

cheers Jim.

No problem just rebooted my router and thought i would try NTL DNS again if anyone in the North West is having problems browsing at the moment .

Its simple change your DNS

ctrl - F5- doesn't that just request the proxy server fetch a fresh page?

I am wondering whether the dns settings have made any difference...?

I would guess that it has, I did mention that I could access my AV suppliers website and get the deffiles using my Zen dial up account but got a DNS error every time using Ntl.

when you say dns error - do you mean page cannot be displayed on internet explorer?

Correct. I had no problems accessing Commands website via Ntl BB but trying to access the deffiles produced a timed out, page not displayed/ poss DNS error. However using dial up from Zen allowed access to the deffiles. I receive auto email notification of deffiles updates but the software should, and did auto update itself until recently. In fact it sometimes updated even before the email notifications. If I left the AV software to its own devices I found that it did eventually update automatically 3 or 4 days later, presumably when Ntl's DNS servers had updated.

so if you changed dns servers back and pressed ctrl F5 would that download the defifles? it may just be a proxy problem or even settings on ie - is it set to check for newer version of stored pages every visit?

Proxies have been turned off in the N/West for a long time, and IE is set to automatically check for new pages. There have been no deffiles updates since I changed DNS so I will see if the next auto update proceeds on the same day with the new DNS,and try your suggestion for the subsequent deffiles update.

if the proxies are off then it must be dns as you said...
