Sorry, I should have thought of that. You only changed the location of some of your folders, not your entire user profile. So, i should have just said - look at c:\users\kevin to compare.... good thinking on your side.
I don't know of any easy security copy - that doesn't mean there isn't one. There are only a few settings that need to be checked/changed so it isn't that difficult to do by hand.
The easiest by hand method is to have both properties up and simply change D:\Users\Kevin to match C:\Users\Kevin.
tip: I keep the reference properties on the left side (c:\) and the one I'm modifying on the right side (d:\) of my monitor since I read left to right.
