When capturing (mounting) and ISO in shared mode to a VM in System Center Virtual Machine Manager I received an access denied error.
The error was the following:
VMM cannot complete the Hyper-V operation on the server.domain.local server because of the error: 'SERVER' failed to add device 'Microsoft Virtual CD/DVD Disk'. (Virtual machine ID 04AA0CF7-E715-41F0-AC9B-2496CE31FE20)
'SERVER': User Account does not have sufficient privilege to open attachment '\\LibraryServer.domain.local\VmmLibrary\ISO\ISOFile.iso'. Error: 'General access denied error' (0x80070005). (Virtual machine ID 04AA0CF7-E715-41F0-AC9B-2496CE31FE20)
(Unknown error (0x8001))
Capturing in non shared mode works without any problems.
Microsoft have described the problem and the solution in the following KB article http://support.microsoft.com/kb/2285882
The solution is to add the HyperV host to the Active Directory group called "Windows Authorization Access group" placed in the built-in container.
I had to reboot the HyperV server before it worked even though it is not mentioned in the KB article.
