The file d:\virtual machines\disk.vhd does not have the required security settings

In virtual server 2005, you could copy VHDs among different folders and virtual servers no problem. With Hyper-V if you tried this, you will get an error similar to: The file d:\virtual machines\disk.vhd does not have the required security settings.

What you need to do is deattach the VHD file from the virtual server settings, and then reattach it. This is because there are special security permissions that need to be applied on the VHD file. These permissions are the XML file filename, so the only way I know is to just remove VHD, and readd VHD file.
