RDS/Terminal Server IE Security Zones

Thank you in advance for all you help. I have a number of sites that are configured on the users profile on their windows 7 desktop via GPO for IE security levels and that is setup and working as expected.

Each user also has a Terminal Servies/RDS on my servers that is used as well for remote access. The server is a Windows 2008 R2 Enterprise running RDS. The sites do not get setup correctly under RDS.

Please help me figure out how to setup the sites under RDS as the are on the desktop. Thanks!

simply create an OU for your Terminal servers and link the GPO you created for your users.


    Create a GPO for your IE settings, link it to the Terminal Services OU.
    Open GPO for IE settings
    Navigate to: User Configuration\Policies\Windows Settings\ Internet Explorer Maintenance\Security
    Change settings and click OK.
    Test by running gpupdate /force or have log off/on the Terminal Server.

The IE Security settings are somewhat flaky and may not apply properly.

If the inherent GPOs do not work correctly for you, you should configure Group Policy Preferences / Registry in order to force the settings via registry.

The other critical piece to becraig's solution is to make sure you enable Loopback processing in your group policy settings - It will be in the machine section, administrative templates, (I think under System/Group Policy).  

By default, the policies on the machine's OU will only process the machine settings.  The user settings are ignored.  However, Loopback changes that behavior.  If you have loopback turned on, then 1 of 2 things happens, depending on which model you pick.

1. Merge -the machine policies are applied, the user's policies are applied, and then the user policies from the machine's OU are applied.
2. Replace - the machine policies are applied, and then the user policies from the machine's OU are applied, and the user's OU policies are ignored.

I've used the IE maintenance settings for years without any issue.  *HOWEVER*.. and this is a big one... the IE Maintenance policies are *not* used with IE10 and above.  Only IE9 and earlier will use those policies you are setting.  If you need to use IE10 and up, then you need to use the Group Policy Preferences section to apply your settings.

I configured the loop back and that did not work. I also configuered the user setting in the TS user settings to match the default policy user settings.

I got an message about upadting the .adm files, but when I looked at the MS site the .adm files they show as current are from 2008.

This is the exact error I get when running a gpupdate / force

"Updating Policy...

User Policy update has completed successfully.

The following warnings were encountered during user policy processing:

Windows failed to apply the Internet Explorer Zonemapping settings. Internet Exp
lorer Zonemapping settings might have its own log file. Please click on the "Mor

Computer Policy update has completed successfully.

html from the command line to access information about Group Policy results."

The Settings are currentky in user config/Admin Templates/Interenet explorer/Internet control Panel/Security/Site to Zone Assignement.

Any thought?

Did you confirm the IE version?
Can you post your file from the gpresult /h?

IE ESC is painful to configure via GPO.  Another case where the GPO just doesn't "listen" to what it's being told to do.  It reverts back to enabled -- and is there anyone that keeps IE ESC enabled???

Set these items via registry GPP for computers:
1. Disable IE ESC for admins:
Action Update
PropertiesHive HKEY_LOCAL_MACHINE
Key path SOFTWARE\Microsoft\Active Setup\Installed Components\{A509B1A7-37EF-4b3f-8CFC-4F3A74704073}
Value name IsInstalled
Value type REG_DWORD
Value data 0x0 (0)

2. Disable IE ESC for users:
Action Update
PropertiesHive HKEY_LOCAL_MACHINE
Key path SOFTWARE\Microsoft\Active Setup\Installed Components\{A509B1A8-37EF-4b3f-8CFC-4F3A74704073}
Value name IsInstalled
Value type REG_DWORD
Value data 0x0 (0)
