Rob shows us the steps to troubleshoot “the errors that pops-up when you try to mount ISO files that sit on a common file share within organization from remote Hyper-V management console”. He says — “If I mounted it from the Hyper-V host Hyper-V management console everything worked as expected.” This stumped me for a while, but then I got to thinking. Where had I seen this before…. Virtual Server 2005. Constrained delegation of authority settings on the Virtual Host objects was necessary there in order to both mount remove ISO images and in order to manage the virtual hosts from a common management web page. So I made similar modifications to my Hyper-V host objects and now all seems to be working correctly. At source are the steps I took to make mounting ISO images with my remote Hyper-V management console, work like a charm.
