Valid patterns and verification of Internet Zone Mappings in IE8/IE9 and W7

Microsoft has added some new options in the Server 2008R2 GPO's for Windows 7 to handle Intranet or Proxy bypass Sites automatic as Local Intranet. But still there is lot of work and trouble. You may have to fix Attachment User Policy for .EXE/.CHM Files and also as usual the Intranet Zone Files.

You can manually check on the Windows 7 client if you have no permission as user. Most of the times the VIEW of the ZONING is forbidden for regular Domain user and you can't scroll down. Just verify in the Registry as user if YOU can start regedit or other reg dump tools.
