RDP Control Fails on Windows XP

Date: 06/29/2009
Revision: 1.1

Problem

When you attempt to launch the RDP function from the Enterprise Random Password Manager or Random Password Manager password recovery website, you receive the following error:



Cause

The inability to launch the RDP function from an XP system is due to Microsoft Security Policy on XP first introduced in Windows XP Service Pack 2. Specifically, there is a default setting in the registry that blocks the RDP control. The registry setting is documented here: http://msdn.microsoft.com/en-us/libr...50(VS.85).aspx.

Resolution

If your system is a standalone system or it is not preferable to set a group policy, The issue can be fixed by deleting the following registry key from the registry:
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Ext\Settings\{9059f30f-4eb1-4bd2-9fdc-36f43a218f4a}

If your system is in a domain where you can configure a gorup policy or you would rather configure a local policy that will affect their XP systems:
  1. Open the preferred policy and enable the following policy: User Configuration\Administrative Templates\Internet Explorer\Security Features\Add-on Management\Add-on List


  2. Click SHOW, then ADD


  3. Add the CLSID noted above to the name column, then put in a value of 1.


  4. Then click OK to add the setting.


  5. Then click OK to add the policy setting.


  6. Click OK to close the policy setting.
  7. Policy will then take effect on the target systems after a group policy refresh or a couple of user logons. Policy refresh can also be forced without a logon by typing “gpupdate /force”.
