Windows 7 Group Policy created icons disappearing

I have a logon VB script that creates desktop icons on our users pc's for some commonly used links.  For whatever reason sometimes when they log on some of the icons are not there.  They log off and back on and they appear.  This seems to be only related to windows 7 machines.  Do you know of any issues with 7 that would cause this or is there something wrong with my script.  Here is a copy of my script.  THank you
