Hi Guys, I've got a problem with some of the .VHD's in Hyper-V. I added a bigger HDD to use exclusively with Hyper-V, I moved all the .VHD files to an external drive, added the new HDD, setup Hyper-V to use the new HDD and moved all the VHD's back, everything appeared to go fine. But now i've noticed two of my .VHD's won't load, I get an 'access denied' error. I've looked at the permissions on the .VHD's and there are some users missing (one with a load of numbers and one named Virtual Machines) on the two non-working files. Neither of these users are listed on my machine so I can't add the permissions. Anybody got, any ideas. Thanks.
