It is possible to create a wildcard webserver certificate using your internal Enterprise CA based on Windows Server 2008 R2. To do this you need to have a Enterprice CA with the webserver template deployed.
The question you'll probably ask yourself is "Why do i need this?". Well the answer is simple. You probably don't want to use this certificate in a production environment, but you can use it for testing purposes without having you to buy a expensive commercial wildcard certificate. Espessially when the test results are having you deciding that a wildcard certificate is not the way to go.
