 When Windows (XP) starts up and I log in, mapped network drives are not
 accessible until they have been "browsed". I.E. if I open QuickBooks or
 any other application and select a "Recently Used" file that exists on a
 mapped network drive, it says the file is not accessible. However, if I
 select "open" and select the mapped drive it will then connect.
