How to add URL to the trusted zone in Internet Explorer?

Question

How can I add an URL to the trusted site? It seems that there are stored in the registry, but where exactly?
The hints I've googled so far weren't helpfull.

The .net programm will run locally on each client.

Edit clarification: I want to do this programmaticly running C# code.

Check this solution at CodeGuru forums.

In summary, this code uses the COM library, a library which you did say you wished to avoid. However, there is no workaround this situation. Another thing to mention is that this code is written in C++, as the guy who wrote it, CorithMartin, ported it from C#.

#include "windows.h"
#include "stdafx.h"
#include "urlmon.h"
#using <mscorlib.dll>
#include <atldef.h>
#include <atlconv.h>
using namespace System;
using namespace System::Runtime::InteropServices;
#define MAX_LOADSTRING 100

int _tmain(int argc, _TCHAR* argv[])
{
    // constants from urlmon.h
    const int URLZONE_LOCAL_MACHINE = 0;
    const int URLZONE_INTRANET = URLZONE_LOCAL_MACHINE + 1;
    const int URLZONE_TRUSTED = URLZONE_INTRANET + 1;
    const int URLZONE_INTERNET = URLZONE_TRUSTED + 1;
    const int URLZONE_UNTRUSTED = URLZONE_INTERNET + 1;
    const int URLZONE_ESC_FLAG = 0x100;
    const int SZM_CREATE  = 0;
    const int SZM_DELETE  = 0x1;

    HRESULT hr;
    IInternetSecurityManager *pSecurityMgr;
    LPCWSTR sites = SysAllocString(L"http://*.mydomain.com");

    CoInitialize(NULL);

    hr = CoCreateInstance(CLSID_InternetSecurityManager, NULL, CLSCTX_INPROC_SERVER, IID_IInternetSecurityManager, (void**)&pSecurityMgr);

    pSecurityMgr->SetZoneMapping(URLZONE_TRUSTED, sites, SZM_CREATE);

    pSecurityMgr->Release();

    return 0;
}

Solution 4

Powershell

#Setting IExplorer settings
Write-Verbose "Now configuring IE"
#Add http://website.com as a trusted Site/Domain
#Navigate to the domains folder in the registry
set-location "HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings"
set-location ZoneMap\Domains

#Create a new folder with the website name
new-item website/ -Force
set-location website/
new-itemproperty . -Name * -Value 2 -Type DWORD -Force
new-itemproperty . -Name http -Value 2 -Type DWORD -Force
new-itemproperty . -Name https -Value 2 -Type DWORD -Force

Solution 5

It lies indeed in the registry, and it's described right there:

Beware of the UAC in Vista though. It's a real pain to deal with.
