如何让GPO知道应用程序？

Question

I'm writing an application in Delphi 2010, and I'd like to provide the option to the administrator to configure it via Group Policy. Any recommendations on good ways to make my application GPO aware? Note, I am only looking to create a computer based GPO, not user.

My current solution involves simply first determining if any values have been written to the registry at HKLM\\software\\policies\\MyProgram . If they have, I assume that GPO has been applied and I use this location to read configuration.

If nothing exists at the above registry location, I proceed to reading configuration at the standard location, whether that's an INI file, or another reg key does not matter. At this point, I make the assumption in the program that group policies are not being used.

Would anyone suggest a better way to make this application GPO aware?

Answer 1

It's not that you have to be group policy aware, it's that the group policy has to be aware of the registry keys your program uses.

The purpose of custom Group Policy Templates is to have a user-interface for managing a custom set of registry keys used by a particular program. The domain administrator sets the policy to the desired values, and the policy is pushed out to machines on the domain.

In your case, the custom policy template will define the corresponding HKLM registry keys that your program uses. You can now trust that the values stored in:

HKLM\Software\MickSoftware\My Program 2010

are what the administrator has desired be there.

Note: The following "policy" registry locations are non-persistent:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies
HKEY_CURRENT_USER\SOFTWARE\Policies
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies

"This means that when you log off the computer or when you shut down the computer, the policy settings are removed."

So it seems to me you want to store your registry values where you normally store them, eg:

HKLM\Software\Avatar Software Creations\HelpDesk\DatabaseServer
    ServerName: REG_SZ = "lithium"
    UserID: REG_SZ = "helpdesk"
    Password: REG_SZ = "aSBsb3ZlIHlvdSBLaXJzdGVuIFNoZWxieSBHdXllcg=="
