Weird Windblows - IE gets different dns to cmd ping
« on: November 01, 2005, 12:21:15 AM »
Hi,
I have a wierd problem - that has me staring in amazement. I must be missing something, but I dont know what. I am sure that I will be embaressed when someone slaps me with an answer.


Scenario
SME 6.0 - basic with antivirus contrib only. Setup as server/gateway.

Server thinks its called chief.x.com and that the remotely hosted web site www.x.com is at address 1.2.3.4.

Then theres a few Winblows XP clients.

Client machines can see www.x.com just fine via the specially defined host name.
System is 3 years old - only down for power outages.


Problem
We change from dial up to ADSL 2 - hooray. Everything runs brilliant. Three weeks later..... We cant see www.x.com from the Windblows clients.

At the server
lynx www.x.com -> see external website
ping www.x.com -> get the 1.2.3.4 address of the external website

At the Windblows clients
command prompt - ping www.x.com -> get correct ip for www.x.com - confirmed same as server and same as external machine 100km's away.

IE and freshly installed Firefox - browse www.x.com -> gets start of admin page for the domain, not the web site. The admin pages are at a different address to www.x.com say 1.2.3.6

It looks like -> Windows is getting different dns results for http requests than for command line pings - WHAT? But that surely cant be.

Have flushed windows DNS cache.

Worse still my old faithful laptop behaves the same way at that office - but works as intended at other similarly configured offices. Hey I got a few of them and they have been there for 3-4 years.

It's gotta be the server... but where? I am still stuck at dns is the same for all applications....

Q: Why wont web browsers go to the same site that lynx does?


thanks
