open file - Security Warning

[Guest dfranklin88]

Greetings,

 

We recently installed IE7 across our Windows 2003 Terminal servers and PC's.

One of our critical apps which runs from a network shortcut now displays an

"open file - Security Warning" before it can be run.

 

We have run into this before and usually add the location of the share to

local Intranet trusted sights. However in this instance it does not appear

that we can use that method to remove the warning message.

 

I have tried: Local Intranet - Sites - deselect "auto detect Intranet

network" and other combinations of options in this area. None of which make a

difference.

 

I have found that: using this commad works "cd %userprofile%\desktop,

icacls links /setintegritylevel (CI)low" but am unsure how to port this

across our domain.

 

I have also found that adding this reg entry works "Local Computer

Policy\User Configuration\Administrative Templates\Windows

Components\Attachment Manager and enable "Default risk level for file

attachments", and then enable "Inclusion list for low risk file types", but

would welcome advice on if this setting is dangerous to have permantly

enabled.

 

Help much appreciated.

 

Thanks
