Remote Desktop "Windows Security" item does nothing - why?

[dmgauntt2002]

I have built a target device that I need to be able to connect to by
Remote Desktop. The connection work fine, but the "Windows Security"
item does nothing when I click on it - neither Task Manager nor the
Windows Security dialog.

I have another target image with "Windows XP Explorer User Interface"
and "Shell Application Compatibility" components, and the "Windows
Security" item works in that image; however, it is too large to fit
onto my Flash Disk.

Can anybody tell me what component(s) I need to add and/or configure
to get the "Windows Security" item to work without bloating my target
image?

Interesting.. That icon does nothing but a call to Winlogon to either show the Gina UI or launch Task manager (depends on a system
policy setting). The cal seems to depend on some systray functionality, though.

If the icon doesn't work, I can only think of a few things:
- You are not using Winlogon (Unlikely since you are RDP'ing into the box),
- You are using a custom Gina,
- taskmgr.exe is missing from your image,
- Tray support is excluded from the image,
- Are the [HKLM\SOFTWARE\Microsoft\Windows NT\ CurrentVersion\Winlogon],"Welcome" and "LogonType" values present at run time?
What they are set to?
- What happens if you just press Ctrl-Alt-Del when you are in and out of an RDP session?
- If you use ProcessMonitor (or Regmon) tool from www.sysinternals.com do you see winlogon.exe being invoked (reading Winlogon
policies settings in registry) at the time you click on the "Windows Security" icon?

Thanks for your suggestions. It looks like the problem is that
taskmgr.exe is missing. However, I have two GINA.DLL files
(MSGINA.DLL and SHGINA.DLL) in Windows/System32 in both images (the
non-working and the working image). I'm not sure why neither of those
are working, but at least I know what to start looking for. Besides,
I can add taskmgr to get the basic functionality I need

DETAILS

For the sake of simplicity, I will call the target image in which the
"Windows Security" icon works the "working image", and the other is
the "non-working image".

If the icon doesn't work, I can only think of a few things:
- You are not using Winlogon (Unlikely since you are RDP'ing into the box),

That is right; I am using WinLogon with Automatic Logon

- You are using a custom Gina,

No custom GINA.DLL

- taskmgr.exe is missing from your image,

BINGO! taskmgr.exe is missing from the non-working image, but not the
working image.

- Tray support is excluded from the image,

Little bingo. The "Tray Icon Add/Remove Support" component is not in
the non-working image, but is in the working image. How does this
affect the "Windows Security" dialog?

- Are the [HKLM\SOFTWARE\Microsoft\Windows NT\ CurrentVersion\Winlogon],"Welcome" and "LogonType" values present at run time?
What they are set to?

LogonType is set to 1, and Welcome is not present.

- What happens if you just press Ctrl-Alt-Del when you are in and out of an RDP session?

In RDP, the host computer Task Manager comes up. Out of RDP, nothing
happens when running the non-working image. Of course, I would expect
that with taskmgr.exe missing.

- If you use ProcessMonitor (or Regmon) tool fromwww.sysinternals.comdo you see winlogon.exe being invoked (reading Winlogon
policies settings in registry) at the time you click on the "Windows Security" icon?

WinLogon is reading lots of stuff from the registry then. The
following reads fail, however:

HKLM\Software\Microsoft\Windows NT\CurrentVersion\WinLogon\GinaDLL
HKLM\Software\Microsoft\Windows NT\CurrentVersion\Policies\System
\LogonType
