I have a need to add website to trusted Zone by .inf

I can use :

[DefaultInstall]
DelReg=Del.Settings
AddReg=Add.Settings

[Del.Settings]
;display the url in the registry
HKCU,Software\Policies\Microsoft\Internet Explorer\Toolbars\Restrictions,NoNavBar
;add url to trust site [2], from type REG_DWORD
HKCU,Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\192.168.1.87
;allow unsave activeX in trust site [2] ref [1201], from type REG_DWORD
HKCU,Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\2,1201


[Add.Settings]
;display the url in the registry
HKCU,Software\Policies\Microsoft\Internet Explorer\Toolbars\Restrictions,NoNavBar,0x00010001,1
;enable unsave Active script to be run
HKCU,Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\2,1201,0x00010001,0
;add url to trust site [2], from type REG_DWORD
HKCU,Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\192.168.1.87
HKCU,Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\192.168.1.87,http,0x00010001,2


My problem is:
I can see 192.168.87 in Trusted Zone of IE8, But I can't use/delete it.
after I run the inf file, I can't use wscript.shell
But When I add the web site from IE8 interface to the trusted zone; I can use wscript.shell without any problem

What I miss, Please advise me.
If I am in the wrong place, please advise me with the right place.

Thank you.
