NTL DNS proxy related problems?
 

When I use the NTL DNS proxy (you know the thing that looks up ip addys)
I seem to get 2 problems occur.

1. When I use the Back button on IE the page looses its formatiing, (cant think of a better term). It only happens when I use the NTL DNS but not on others.

2. Yahoo groups, cant process, yet ok when using another DNS server.

anyone know the cause or the solution? or having similar probs?

Re: NTL DNS proxy related problems?
 

I've been having problems accessing some sites when using the NTL DNS servers. No problem at all when I specify non-NTL DNS servers.

Re: NTL DNS proxy related problems?
 

I think you're confusing DNS servers with proxy/cache servers, which are different.
I'm pretty sure that it would be a dodgy proxy that would cause these problems.

Re: NTL DNS proxy related problems?
 

ring up and report it if its a dodgy proxy

Re: NTL DNS proxy related problems?
 

I cant see that a DNS server will cause that kind of web page fault.

Must be a proxy m8.

Re: NTL DNS proxy related problems?
 

Cheers for the advice, wasnt sure if DNS and Proxy where the same.
Does anyone know why it would cause the page to loose its formatting when going back?

Dont forget to report to TS and local francvhise info here

Re: NTL DNS proxy related problems?
 

Just to confuse matters, it should be known that although DNS servers and Web proxy servers have separate functions, most Web proxies (and even some web browsers) cache DNS lookup information. This can make it pretty confusing when it comes to trying to track down these problems.


As an example a few months ago when NTLs DNS servers were effectively dead from here, you could still browse to certain web sites if you picked specific NTL proxies. This only worked for common websites and as time went on stopped working, I guess because the proxy DNS cache timed out the cached DNS entries and tried to refresh the entries.

Entering alternative DNS servers in your own settings can often fix NTL DNS problems but not always. I guess it depends on the priority of lookups which I have yet to fathom out.

I'm still having problems with the back button when using an NTL default proxy and am not sure if I've explained the problem properly?
Below is an example of how Cable Forums looks when I use the back button on an NTL proxy.

And here is how it should look normally

Hopefully this will help explain the problem better and pinpoint whats causing the trouble.

try deleting your temp internet files - it maybe your browser cache that is corrupt - tools > internet options > delete files

Re: NTL DNS proxy related problems?
 

Tried it but didnt make a difference, thanks anyway.

It only happens when I don't specify a proxy, took me a while to realise that was a common factor. At first I thought it might have been another program like google toolbar causing the problem but I've tried removing that and other IE add ons too no effect.

Re: NTL DNS proxy related problems?
 

Well the problem is probably to do with the WCCP (Web Cache Control Protocol), this is the redirection that is put on the outbound interface of the t2core routers toward the bb routers or the inbound interface from the t2cam or dam routers. But you'r probably just reporting that the problem only occurs when you don't specify a cache :erm:

- its probably redirecting you through a different Cache each time or something silly.....

Have you tried a different browser (just to cover all possilibities?)

Re: NTL DNS proxy related problems?
 

I only have IE6 so can't try another browser, but yes it only happens when I dont specify a proxy.
I was thinking it could be a bad reg entry but HiJackThis has found non out of place.

Re: NTL DNS proxy related problems?
 

In other words its time NTL found another job for the transparent cache and turned them of for good. Instead of wasting resources using them when they are unable to cope. There must be something else these can be used for that is more benificial to the company....

Re: NTL DNS proxy related problems?
 

zendawn - maybe you should download Mozilla, Opera or Netscape??!

Herm debatable, caching is important and does have advantages - it will speed up the browsing experience if implemented correctly, the problem is with the caches being slow because they are either over loaded or not load balanced correctly...and again with them caching stale copys of data.

Not all the problems are down to the caching some is down to issues with Cisco's WCCP redirection protocol, Also, I think you will probably find that the caching has got better since NTL implemented Network Appliance caches instead of the Inktomi ones.

If NTL turned the all the caches off, the network would probably grind to a halt. Most large networks use caching - Just look at the SuperJANET Web Cache Service .

Unfortunately caching is here to stay on nearly all networks not just NTL's. It's about NTL and other companies configuring it correctly.

Re: NTL DNS proxy related problems?
 

UPDATE:

I've downloaded and installed netscape, as recommended by slimshady, and the problem doesnt happen when I use it.
Does this mean it's a problem with my configuration of IE or is it still as I suspect a proxy problem?

Re: NTL DNS proxy related problems?
 

Confusing..... - thats really wierd - it could be IE but then again it might be the damn caches :S - I'm probably a bit stuck here - What version of Windows is it? - I am assuming XP - maybe try running Windows Update and Scandisk and then deleteing the temporary internet files...also might be an idea under XP to try under a different user profile??!?!

Re: NTL DNS proxy related problems?
 

I'm using Win98 and IE6.
I've ran windows update earlier today and still no joy.
The only thing I can think of is a rogue reg entry causing a conflict somewhere, it seemed to happen after installing google toolbar, but I've used hijackthis and weeded out most of the entries I can do, but still no change.

Re: NTL DNS proxy related problems?
 

Have you tried running adware to check for rogue registry stuff?

Re: NTL DNS proxy related problems?
 

Yes and RegClean.
I can use Netscape or set a non NTL proxy to get around the problem, but I like trying to figure out the cause of this type of problem.

Re: NTL DNS proxy related problems?
 

Not any more....

"The JWCS would like to advise you that the National Cache Service has now closed as of 3rd December 2002."

Re: NTL DNS proxy related problems?
 

Maybe, Theres still caching at nearly every institution on SuperJanet tho... I was just diging that out for some reference. Tho I believe most of the time they just close port 80 and make you specify a proxy.

Re: NTL DNS proxy related problems?
 

So were not getting much nearer to find the answer.

Have a look at the proxy list on

http://homepage.ntlworld.com/robin.d...cache.html#ntl

and see if any of the "Ink" ones make any difference.

Re: NTL DNS proxy related problems?
 

I'm not sure if I'm doing it right?
But if I set ( 195.40.1.250 ) as the proxy in the My Connection Settings section I dont get the problem occur.
If i type ( cache1-brtn.server.ntli.net ) as a proxy in the LAN settings I still get the problem. :dunce:

Edit: Just used ( cache1-brtn.server.ntli.net ) in the MY Connection Settings Proxy section and problem is not happeing. Solved problem but still not sure of cause. :tu:
