Looking in the Hosted Services, Storage Accounts & CDN, under Management Certificates, I see my one Subscription and the Subscription ID, but the Thumbprint is blank. I need the thumbprint in order to upload my VHD. Why is it missing? What do I need to do to get it? Thanks!
Have you specifically created a management certificate? If not the easiest way to do it is to use the Visual Studio Azure SDK and from in there go as if you were deploying an application. It will walk you through the steps for adding a management certificate. Alternatively you should be able to find more information from this blog post.
