could you be a little more explicit when you say, personal folders are changing to my documents?
You mean that any random folder a user creates, can/will/has probability to change its name to "My Documents" and the folder icon becomes the Paper icon?
And, are these goofy changes happing when the client logs into a computer, or are you noticing these problems on the server side of things?
If this is the case, then the problem is associated with "desktop.ini" files. i would check the folders for "desktop.ini" files, rename every one of them (with a dash or somethin in front of their names) [make sure you enable hidden system files/folders, ect, in folder options and for what to search for). this will start to eliminate the folders when they change to "bob's documents" and other things.
next i would check to make sure (a specified, or all, or a little sample) of the user's Document folder actually points to the proper path, and if not, maybe the whole lot was corrupted somewhere/how and the server(maybe clients) system needs to be diagnosed.
