Verify IIS Settings
Follow these steps to verify the IIS settings:

If you do not see ASP .NET under Web Service Extensions, ensure that ASP .NET is enabled in the Application Server. You can do this by going to: Control Panel -> Add/Remove Programs -> Windows Components -> Application Server -> Details.
2. Ensure that the default document for the site is Default.aspx (under the Documents tab).
3. For better performance, set HTTP content expiration for 7 days on the App_Themes folder unless you are actively creating a new skin.
4. In Windows 2003, alter application pool’s performance tab to disable the “Shutdown worker process after being idle for,” or change it to a high value, like 240.

Update DNS
If any domains are already set up with SmarterMail, make sure to update their Webmail DNS records to point to the new IP address.

Test the site
Open up your browser and type the IP address of the site you just added.
