Tired of copying an ISO to a Hyper-V host every time? Tired of getting that General access denied error when trying to mount an ISO located on the network? Here is how to solve that:
Prequisites: Setup your core or full edition Windows 2008 or Windows 2008 R2 and install the hyper-v role (This also works for Hyper-V clusters just add all the necessary computer accounts to the file share and ntfs permissions).
On the server with the shared ISO folder:
Set both the NTFS and the Share permissions to FULL for the Hyper-V computer account(s).
On a Domain Controller:
Open Active Directory Users and Computers (dsa.msc)
Find the Hyper-V server and double click on it.
Click the Delegation tab.
Click Trust this computer for delegation to the specified services only radio button.
Click the Use any authentication protocol radio button.
Click the Add button.
Click the Users or Computers… button.
Type the name of the Fileserver and click the Check Names button. An underline will appear under the name of the Fileserver if the correct object was found in Active Directory.
Click on the cifs Service Type and click the OK button.
Click the Apply and OK buttons.
Note: it takes a few minutes to actually work. If after 5 minutes it still doesn't work reboot your Hyper-V box and try mounting an ISO again.
