After upgrading to IE7 in Windows XP, we found that non-admin users were once again seeing the Open File Security warning dialog box.
Once again, the issue can be resolved by visiting the group policy. Open up the appropriate policy file, and follow the path to:
User Configuration > Administrative Templates > Windows Components > Internet Explorer > Internet Control Panel > Security Page
- Double-click on Site to Zone Assignment and then click ‘Show…‘
- Click ‘Add…‘
- In the Add Item dialog, type in the FQDN of your domain (eg. mydomain.local) in the first field, and the number ‘2’ in the second field.
- Click ‘OK’ until the dialogs are closed.
- Now log a user onto a workstation to check that the changes have taken effect.
All we have done here is added your domain to the Trusted Sites zone, which removes the file security dialog.
Well done, you.
