I am running Vista Home Premium 32-bit. I am the only user; no other accounts are set up. I am trying to shrink the volume of my primary disk using Disk Manager. I right click my c: drive and select "shrink volume", and get the box asking me for the amount of space to shrink. When I then click the Shrink button, I get a dialog box with the header Logical Disk Manager, and the message "Access is denied." There are no codes or explanations, and I am not having any luck finding a solution. Someone posted the same issue on a Microsoft board on 10/30, but no one has responded. Thank you for any suggestions!
