General access denied error when trying to mount ISO's on Hyper-V

Had massive issues trying to mount ISO's from a network share on a Hyper-V cluster a few weeks back and I wanted to take the time to pass on how I managed to solve this pain in backside...


So if you don't set up delegation for the host's you get that lovely "General access denied error" everytime you try and mount a file from a network share, this is what you need to do from Active Directory

From the DC complete the following,

1. Launch Active Directory Users and Computers
2. Locate the Hyper-V host and open it (don't forget to search for "Computers" and not users.)
3. Open the Delegation Tab
4. Click on the Trust this computer for delegation to the specified services only option
5. Click the Use any authentication protocol option
6. Click Add
7. Click Users or Computer
8. From the "Add Services" box click Users or Computers and specify the name of the network share that stores the ISO's and click OK
9. Choose the cifs service and click OK
10. Click OK

Once that's done, you will have to reboot the Hyper-V host, once its back up you will be able to mount ISO's again from Hyper-V manager.
