Access denied when capturing an ISO in shared mode i SCVMM 2008

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:

Error (12700)

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

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. Undecided
