Can you provide some more details on Amazon aws, I've looked into it but was never able to figure out how to setup a virtual server. Thanks.
once you create an account on http://aws.amazon.com/ you then go under the compute section click on EC2. Since you want to use NT, select one of the Windows EC2 instances. And also since you want to try it put first you can choose one of the free tired. It's free for a defined period and amount of data passing through. Once you pass above a certain threshold you then start paying for the band width. It's good for testing. You can also try Microsoft Azure which provides cloud services. Both platforms provide an easy interface for clicking through to setup a server. Once more start with the basic package.
