On mapped drive to Mac, Open File - Security Warning

I just upgraded my XPSP2 VM to IE7 (some of our internal products only worked on IE6).

Now when I run a batch file which is located on my Mac (M: is mapped to \\.PSF\.Home\myStuff) , I get the prompt that suggests this file is not trustworthy, do I want to <Run> it or <Cancel> the request:

Open File - Security Warning
The publisher could not be verified. Are you sure you want to run this software?
name: boq.bat
Publisher: Unknown
Type MS-DOS Batch file
from: M:\utils

I tried the regular things that work with "normal" mapped drives, no joy:

Anyone have any suggestions so this batch file (and every other executables on my mapped drive), start without the prompt?

 

Add this \\.PSF\.Home\myStuff to trusted locations,

 

When I do that, I get "That site is already in the Trusted sites zone.", however it is not in the list of "websites"

1. start.Run (inetcpl.cpl)
2. click <Security> tab
3. click <Trusted Sites> icon
4. click <Sites> button
5. type "\\.PSF\.Home\myStuff" (also tried "\\.PSF\.Home")
6. click <Add>
7. get message above
