Shortcut to IE9 32-bit points to homedrive instead of c:\program files (x86) on Win7 x64??

Strange problem here. We are deploying Win7 SP1 x64 using SCCM OSD. In the base image i've included the IE9 installation. When deploying this image and logging on for the first time the shortcut to the 32-bit IE9 points to H:\Program Files\Internet Explorer\iexplore.exe instead of to C:\Program Files (x86)\Internet Explorer\iexplore.exe

I've observed the following:

• The driveletter of this users homedrive is H:
• When logging on with a local user account (administrator) the shortcut is fine!
• the folder on H: does not exist
• x64 IE shortcut works fine
