About Virtualization, VDI, SBC, Application Compatibility and anything else I feel like

I was just researching a little on how Group Policies are applied in Windows Vista. The client processing is actually done by the Group Policy Client Service. So can a user prevent Domain Policies from being applied by stopping this service?

If you go to the service properties you can see that even a local administrator cannot stop or disable the service:


The description says: “The service is responsible for applying settings configured by administrators for the computer and users through the Group Policy component. If the service is stopped or disabled, the settings will not be applied and applications and components will not be manageable through Group Policy. Any components or applications that depend on the Group Policy component might not be functional if the service is stopped or disabled.”

That sounds good! Let’s try it…

    Beta ReleasePart 1Part 2  

    This is part 3 of the TSAdminEx Features series. Today I will discuss the Process View. As usual we will start by comparing TSAdmin to TSAdminEx again. So let’s look at TSAdmin Process View:


    And the one from TSAdminEx:



    TSAdminEx Features Part 2


    Now that a TSAdminEx beta is ready I will be showing you some features. In this part I will show the Sessions View.

    Let’s start again with a compare of TSAdmin and TSAdminEx:



    As you can see TSAdminEx shows more details, it shows the following extra columns:


    TSAdminEx Features Part 1

    Part 2

    Now that a TSAdminEx beta is ready I will be showing you some features. In this part 1 I will be comparing the Users view to TSAdmin.

    Let’s start TSAdmin, this tool is present by default on Windows 2003. If you use Windows XP or Windows Vista you can get it by installing the Administration Pack. Please note that TSAdmin does not work on Vista RTM due to a bug that was corrected in Vista SP1 (TSAdminEx works fine on both RTM as well as SP1)


    Now let’s open TSAdminEx and start comparing…



    TSAdminEx Beta release

    Over the last months I have been working hard on TSAdminEx and now, finally, I can now present a first beta release.

    If you don’t know what TSAdminEx is let me briefly introduce it. TSAdminEx is a tool that combines functionality of several existing tools: it has the power of task manager combined with the details of Process Explorer and the Terminal Server support of TSAdmin. On top of that it fully supports remote systems out of the box without installing any agents or services. It also has some unique features that neither of the mentioned tools can do!

    Several new features have been implemented since the last time I talked about TSAdminEx and I will show you the most exciting ones here:


    In part 1 I showed how to create and open objects in Terminal Server Sessions. However, these are not all of the possible places where you can place objects via documented kernel32.dll functions.

    If we look into Winobj again, we notice, that every BaseNamedObjects directory has a subdirectory named Restricted. To be honest, I do not know why it’s created; it’s security allows object creation for LocalSystem and RESTRICTED special user (in windows 2000, Everyone can also create objects in it). So, we can use it as prefix for object creation, for example, Restricted\MyAppEvent: RestrictedObject

    Of course, you can still use Global, Local, or Session links (more…)
