IE Problem

[djones2002]

Howdy.

Been having trouble for quite some time using IE6 (with latest patches). The problem is when I try to go to certain websites, I keep getting the standard "Server could not be located...check your DNS settings...yada yada yada". If I hit refresh 2-3 times, the error will sometimes go away. If not, I try again later, and the problem goes away.

I clear my disk cache, delete my cookies, etc; Yet, the problem seems to happen with at least one site every day. The biggest problem site being msnbc.com

Is there something I can do mitigate this problem? Like a static DNS entry, or something? Driving me up a wall.

Sometimes sites are busy.

One thing you can do, but it may not be your particular issue, is update your SSL CA certificate: thread608-4650

It possibly could help to adjust your negative DNS cache time.

XP remembers negative (DNS unable to resolve) entries for a few minutes. Often this can be a pain when moving and debugging sites. As long as that negative entry sits in your DNS cache, your box will continue to give you a cannot find server error. By cleaning out your DNS cache, you can fix this problem.

Rebooting will flush your cache... but there is an easier way.

Drop to a command box and type:
ipconfig /flushdns

If you wish to stop Windows from placing negative entries into cache, you can make this change in your registry.

1. Goto HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters
2. Build a new DWORD value called NegativeCacheTime and give it a value of 0
