I have Windows XP. This is my home computer. I have three screens (myself, my wife and my daughter) each of us use our own screen with separate user names and passwords. I am the Administrator, I can have access to my dauters file and carry out scans etc. Howevere, when I try to go to my wifes files it tels me "Document is not accessable Access dinied". I cant virous check etc. How can gain access.
