I recently installed Win10 Pro on a spare workstation that I had available to me. The install seemed to go pretty well the second time around as the first time it failed for some reason. In any event the second install worked fine and I was able to login to the local machine and enable the local Administrator account etc. Then I joined the machine to my domain here in the office which went fine after which I restarted and logged in using my domain admin credentials. I was logged in but when I tried to configure my normal settings on the desktop I received errors. Whenever I try to go to Personalize > Themes > Desktop Icon Settings I receive the error C:\Windows\system32\rundll32.exe Windows cannot access the device, path, or file. You may not have the appropriate permissions to access the file? Now I am logged in to the workstation as the Domain Admin I should have full and complete rights to do whatever I want? When I login to the local machine as the local Administrator I do not get the same error??? I have Googled and have not found anything as of yet on this issue? Any assistance would be greatly appreciated.
