As DotNetMensch said but you DO NOT need to add another site in IIS as this can also cause further problems and make things more complicated because you then have a website within a website so the file paths, masterpage paths and web.config paths may need changing. You just need to edit teh bindings of the existing site and add the new subdomain there.

So:

Add sub-domain to DNS records. My host (RackSpace) uses a web portal to do this so you just log in and go to Network->Domains(DNS)->Actions->Create Zone, and enter your subdomain as mysubdomain.domain.com etc, leave the other settings as default
Go to your domain in IIS, right-click->Edit Bindings->Add, and add your new subdomain leaving everything else the same e.g. mysubdomain.domain.com

You may need to wait 5-10 mins for the DNS records to update but that's all you need.

This one drove me crazy    basically you need two things   1  Make sure your DNS is setup to point to your subdomain  This means to make sure you have an A Record in the DNS for your subdomain and point to the same IP   2  You must add an additional website in IIS 7 named subdomain example com   Sites   Add Website Site Name  subdomain example com Physical Path  select the subdomain directory Binding  same ip as example com Host name  subdomain example com

Wildcard method  Add the following entry into your DNS server and change the domain and IP address accordingly     example com IN A 1 2 3 4  http   www webmasterworld com microsoft asp net 3194877 htm

If your computer can t find the IP address associated with SUBDOMAIN1 example COM  it will not find the site   You need to either change your hosts file  so you can at least test things - this will be a local change  only available to yourself   or update DNS so the name will resolve correctly  so the rest of the world can see it
