another dns trouble

[FALCONSEYE]

I was asked to move a site from server A to server B. The last step was to change the dns A record entry. Now that I changed the A record from xx.xxx.xxx.158 to xx.xxx.xxx.157,

I still cannot see the

http://www.mydomain.com

on the new server. When I ping

http://www.mydomain.com

from my local machine, I get the correct ip address of which: xx.xxx.xxx.157. On the other hand, when I ping the same domain from the server (.157/the dns server), I still get xx.xxx.xxx.158.

I did ipconfig /flushdns and even changed the TTL to 1min and still no luck. Does anybody know what I am doing wrong?

Ok, the problem was dns caching. I did two things: locally, ipconfig /flushdns and on the server:

Now, the next problem I have is that there are a ton of users already. So, how am i going to let every client do the flushdns thing? Is there an easier way of this?
thanks

If you had a long TTL before you changed it to 1 minute, then your windows machines are going to cache it for that period. Also, browser cache seems to always play havoc.

Always a good thing to do is REDIRECT from the old ip

http://www to

the new one ( at the server level). You can also record those ips that seem to use the old ip that way.
