IIS 7 on 2008 R2.
Here's the issue:
In DNS I changed the Alias record for oldsub.mydomain.com to point to newserver.mydomain.com instead of oldserver.mydomain.com.
There was already a newsub.mydomain.com pointing to newserver.mydomain.com.
I want both newsub and oldsub to point to the same site.
Then I went into IIS on newserver and added oldsub.mydomain.com to the bindings on the appropriate site. Now the site has bindings for both newsub and oldsub. There is no SSL.
If I go to newsub.mydomain.com, the desired page will load. If I go to oldsub.mydomain.com, I get the default IIS banner page instead. If I go to oldsub.mydomain.com/default.aspx, the desired page will load.
I've double-checked the binding, even removed and readded it, restarted the site, but nothing is working. I've run out of things to check. any ideas?
Thanks in advance...
