I had my live site working with the name:
mysite.domain.com
and I created a brand new server hosting my test site:
mysite-test.domain.com
My new site is finally ready so I changed the DNS entry of mysite.domain.com to point at the new test site.
I added a second binding in the new IIS
https 192.168.10.10 mysite-test.domain.com
https 192.168.10.10 mysite.domain.com
Unfortunately this bind doesn't work - the page just loads for ages and gives me a 'site not found' error. I tired nslookup and it is resolving to the correct IP. The SSL cert is valid for both hostnames.
Am I missing anything?
Despite nslookup returning the correct IP, rebooting my pc worked.
