Why is Remote Desktop Services missing from Group Policy Management in Server 2008

On the main window add these:

public static MainForm Current;

public string FileLogin
{
    get { return fileLoginToolStripMenuItem.Text; }
    set { fileLoginToolStripMenuItem.Text = value; }
}

Obviously use the name that you set or was automatically set for the menu strip item for the login/logout menu item. then in the form constructor of the main form, set the Current.

public MainForm()
{
    InitializeComponent();
    Current = this;
}

Then from the other window/form you can call (to set the value):

MainForm.Current.FileLogin = "Logout";

But better than this is that you on your child window make an event,

public event Action UserLoggedIn = delegate { };

And on the MainForm have the MainForm subscribe to that event with a reverse of the above...

ChildForm.Current.UserLoggedIn += () => FileLogin = "Logout";

And have the child raise the event when the user logs in, with UserLoggedIn().

Not sure if you REQUIRE the setting to come from local group policy, but if you want to bypass the group policy problems, just set this Registry Key which will be common to all windows systems. The registry path you have is related to the group policy processing which will be different for each machine, so it will be difficult to script. Unless your in a domain I would avoid group policy.

 Windows Registry Editor Version 5.00

 [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services]
 "SelectTransport"=dword:00000000
 "fServerEnableRDP8"=dword:00000001

Place that block into a text file named settings.REG file. You can double-click it or just commit it with:

regedit.exe /S settings.REG

The /S makes it silently install to the registry for scripting needs. I added "selecttransport" because it enables UDP transport for RDP traffic. With this .REG file you'll have the same settings in windows 7 as is default in windows 8.1.
