Our corporate website was run locally on a 2003 box using iis6. Due to DR we decided to have this hosted externally with a web hosting company. The internal web team created the site and this was setup with the external company.
Within our domain name host company i created all the a records for the 20+ sub domains (sub-websites) and the external website host created the redirections back to our IIS server. I created all the a-records internally and that is all working.
Because i have not made any changes with regards to the old corporate website, internally staff are still getting the internal site when they type www.oursite.com
externally it is working fine.
I need to know the correct process to limit any disruptions to the site for internal staff to pretty much switch off the old internal IIS website and for all requests for that url to start seeking the site externally.If I stop the IIS service for that website, is says “Bad Request (Invalid Hostname)” When I changes the IP address of the DNS entry within the www.oursite.com
for the www entry, that also stops the page loading.
Any assistance would mean less grey hair for me :-)
