Story: We had a project to migrate webserver www.abc.com.au(Melbourne)
to our new site in sydney. After finished migration. I added a new forward lookup zone (save the zone in the AD becaseu DNS server in our DC) abc.com.au with a A host recorder *.abc.com.au as the ip 172.xx.xx.xx. Then i can open webpage from internal to accss our web server. For some reason, i have remove the zone abc.com.au in our DNS because our users need to access the original website in melbourne. Then i delete the zone abc.com.au from Forward lookup zone. The problems are coming:
Problem 1: I can not open the web page of www.abc.com.au
(210.xx.xx.xx)in melboune site
from my PC because when i type www.abc.com.au
in my IE browsers, the web
page still come from the internal web server in sdyney (172.xx.xx.xx).
2: but i can use IE browser to open web page of www.abc.com.au
3: nslookup www.abc.com.au
from my pc, i can see the ip is (210.xx.xx.xx), even i
, the ip is 210.xx.xx.xx
So, is there some one can tell me why? and how can i fix the problem in DNS? Is it dns replication problem?
