UAC problem

UAC problem

Postby patel.mudra » 2011-03-29 07:36

Hello,
I am using UltraVNC 1.0.8.2 Version (Server) and VC++ Client to manage 30 computers in our network.

I am running server exe in usermode(don't want to execute as service)(OS is Windows XP, Windows 7 and Windows Server2008) . When the UAC windows popus up, I no longer have access to the remote desktop.

Then the only way I can give remote support is to physically go the that
machine.

What can I do on the server so that even in the user mode, when I get a UAC popup, I will get the UAC screen in the client. I saw Teamviewer, which we can run in user mode, and this still gives the UAC popup on the client.

Pointers of what I have to do would be extremely helpful.

Not sure, but I don't think that's possible; it's part of the point of UAC to prevent that. You could always just install the service and then uninstall it; it just takes a single command line.

Thanks for the reply.
I saw Teamviewer, which we can run in user mode and they are able to handle UAC popup from viewer side.

Technical it's not possible.

If a user mode application can handle uac protected applications, the whole uac concept would be a fake protection.

If this is possible, a normal user could easy become administrator without the need to enter any password or your iexplorer could install
software without asking the user any question...

I guess teamviewer use a service with a backdoor for the user app to start/stop the service..

not true
have a look at services.msc
you can see TeamViewer Z (z version of teamviewer)
C:\Program Files\TeamViewer\Version6\TeamViewer_Service.exe
service of teamviewer running at background.... for UAC
if not exist, it wait to enter UAC like QuickSupport
