Default Internet Problem

Hello,

Just recently, we have had a weird internet glitch. When a user logs on and opens the internet, it seems to take ages to display the home page, then you get a 404. If you then imediately try again it works. The problem doesn't occur again until they log off.

We are running a ContentCache box, which the computers use as the proxy. There isn't anything on the logs in there.

From there is the ISP's firewall.

It just seems like it taking ages to authenticate on somewhere.

Any ideas?

Thanks

Karl

Cool

Have you checked you dns / forwarder settings, it could be a routing problem. also check see if the computer is picking up all the settings off dhcp.

Can you tell us what your home page is? You could experiment and set it as Google or Yahoo.com which are very reliable. I've seen this behaviour before, and in the end it was a load problem with the servers that were hosting the site!

To verify your workstation config, type
Code:
ipconfig /all
from a command prompt. You should see (at the very least) your primary DNS which should be your domain controller.

Doing IPconfig reveals as expected, DNS set to dc.

Home page is St John's Catholic School for the Deaf Online Learning.

sounds like what you get when you have a toolbar installed. It wont let you view anythign while it loads then once it's on you can see what you want. The 404 will appear moments before it begins to work.

I had a similar problem last year. I found that the home page was being cached by the proxy. Some users got on straight away, some didn't. It was down to the proxy not being able to handle multiple requests at the same time for the same page.

Still not managed to solve this one either. Seems to do it when joined to domain even without toolbars installed. Could it be do to with permissions, IE trying to update itself?
THanks

same as we get here at college, same error its to do with the DNS, but i dont think the tech staff know how to fix it. It also does it on random websites sometimes too, kind of an annoying problem to say the least.

Your primary DNS should be your DC and secondary should be your ISP. It could be that your host is suffering from DNS issues. Presumably everything within your LAN is working correctly? If so, it would appear it's an external DNS issue.

I have to say St John's Catholic School for the Deaf Online Learning. took a while to load for me. It might be machines are timing out at busy times?

Just been on to our isp and they suggest its an internal dns issue.

The client pc's are set up to obtain dns automatically. The DC has dns set to the proxy server (primary), and the router (secondary). Both the router and the proxy server are then set to the ISP DNS's of 212.44.55.100 & 193.164.97.35.

Thanks

Have you tried Wireshark to see what's happening when the browser is pausing?

What software is the cache box running?

How do you set your proxy settings, group policy? Check to see if 'Automatically detect settings' is checked in LAN settings if it is try unchecking it.
