Server 2008 Prevent Users Installing Programs

There are some security advantages to enabling NLA, but one of the drawbacks is that users with expired passwords are prevented from logging on to the remote system. More information about NLA and RDP can be found at the Microsoft site and on Wikipedia.

Users who have not activated offline access are subject to the fail mode setting e.g. if set to fail open, a user who did not activate offline access would be able to log in without completing Duo offline authentication. Disable "fail open" if you want to prevent users who did not activate offline access from logging in when the computer is offline.

Duo Authentication for Windows Logon can be bypassed by rebooting a Windows system into Safe Mode. To limit the effect of this, you should prevent all but a select group of users from logging in while Windows is running in Safe Mode (for example, via the registry DWORD value HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System\SafeModeBlockNonAdmins set to 1).

You may have Windows systems where no users should log in using offline access, regardless of the application setting in the Duo Admin Panel. To prevent offline authentication for any user on a given Windows client, use the Registry Editor (regedit.exe) with administrator privileges to create or update the following registry value:

I've been around Citrix for a long time. I'm used to the following procedure for installing applications:Log onto console of serverKick out all userschange logon /disablechange user /installinstall the applicationchange user /executechange logon /enablePublish the applicationI've pretty much kept this up throughout my implementations of XenApp 6. I haven't seem to find any documentation that really tells me if this is still needed for XenApp 6. Can anyone tell me definitively if this process is still needed? Is there an alternate process? I'd love to see some Citrix or MS documentation on this.

I think it would be a best practice to stream the application rather then installing it locally on the server but in case I have to install an application locally on the XenApp server I still do use "Installation Manager"

Application whitelisting using an SRP defines which applications are allowed and prevents unauthorized programs from running, which in turn protects your Windows environment. Whitelisting keeps your enterprise protected from emerging threats while still allowing users to run the applications they need to perform their duties. Application whitelisting will save you time and money by preventing costly downtime, recovery, and remediation efforts.

Current binary versions of R are known to run on Windows 7 or later. R 4.1is the last version that supported 32-bit versions: See Can I use R on 64-bit Windows?.R 4.2.0 requires the Universal C Runtime (UCRT), which is included inWindows 10 and Windows Server 2016 or newer. On earlier versions of Windows,UCRT has to be installed before installing R. UCRT is available for Windows sinceWindows Vista SP2 and Windows Server 2008 SP2. Windows XP is no longer supported.

There are two modes in terminal server, Execute and Install. By default all users are logged on in Execute mode and this means they can run programs etc. When you want to install an Application for use by everyone the Administrator should change to Install mode.

If your users will use roaming profiles, when a new user logs on to a server for the first time, a new profile is created for him by making a copy of a default user profile. Domain joined computers will first look for a network default user profile (stored in the netlogon share on a domain controller and replicated to other domain controllers). If it does not find one in the network share, then it will use the local default profile located on the computer to which the user logged on.

As you offer more ways to present applications to users, delivering user configuration data in the profile gets more complicated. For example, instead of having users logging onto a single desktop and doing all of their work on that local machine, you can now offer full desktops in a session, RemoteApp programs, personal VMs, pooled VMs, and even RemoteApp programs from VMs. Each of these application delivery solutions has a unique environment, and therefore, when using the RDS, we recommend implementing different user profiles for each of these unique environments. The problem with this is that users expect to have the same experience wherever they log on. This is not really possible when users have multiple unique environments.

What's the best way to block users from installing software via gpo? I know we can always make them a Restricted User locally but certain programs won't run under that security profile. Any thoughts? We are running Server 2008 R2.

You can install any tools, including anti-virus programs on your AppStream 2.0 image. However, you need to ensure that these applications do not block access to the AppStream 2.0 service. We recommend testing your applications before publishing them to your users. You can learn more by reading Windows Update and Antivirus Software on AppStream 2.0 and Data Protection in AppStream 2.0 in the Amazon AppStream 2.0 Administration Guide.

AppStream 2.0 regularly releases base images that include operating system updates and AppStream 2.0 agent updates. The AppStream 2.0 agent software runs on your streaming instances and enables your users to stream applications. When you create a new image, the *Always use latest agent version* option is selected by default. When this option is selected, any new image builder or fleet instance that is launched from your image will always use the latest AppStream 2.0 agent version. If you deselect this option, your image will use the agent version you selected when you launched the image builder. Alternatively, you can use managed AppStream 2.0 image updates with your images to install the latest operating system updates, driver updates, and AppStream 2.0 agent software and create new images. You are responsible for installing and maintaining the updates for the operating system, your applications, and their dependencies. For more information, see Keep Your AppStream 2.0 Image Up-to-Date.

Amazon AppStream 2.0 uses NICE DCV to stream your applications to your users. NICE DCV is a proprietary protocol used to stream high-quality, application video over varying network conditions. It streams video and audio encoded using standard H.264 over HTTPS. The protocol also captures user input and sends it over HTTPS back to the applications being streamed from the cloud. Network conditions are constantly measured during this process and information is sent back to the encoder on the server. The server dynamically responds by altering the video and audio encoding in real time to produce a high-quality stream for a wide variety of applications and network conditions.

Is there a way to prevent users from installing .msi package? Windows Installer is a background service that manages installing and uninstalling MSI-based programs. To block MSI installer, you can turn off Windows Installer using group policy or registry tweak.

A terminal server (also known as a remote desktop server) is a device that allows multiple users to connect to a Windows Server from remote workstations. The remote user can run applications and access data within a local area network (LAN) or a wide area network (WAN). When running an application that is installed on the terminal server, the remote user sees a display of what occurs on the terminal server, and the user's mouse and keyboard commands are transmitted back to the server.

Windows Server 2012 and Server 2012 R2 Terminal Services. Microsoft has identified an issue that may impact applications in a terminal services environment for users of Window Server 2012 or Windows Server 2012 R2. When running applications on a terminal server from a network location, the application could crash for all users when one user logs off the terminal server.

Tip: On rare occasions, we have also noticed that if firms have not set correct permissions to the \Wincsi\FcabData folder, the driver will not work (although this issue usually manifests itself in many other ways as well). Verify that your terminal server users are set up with Full Control of the FileCabinet CS data locations.

Microsoft AppLocker provides out-of-the-box application whitelisting (AWL) capabilities that prevents users from running possibly dangerous applications. Application Whitelisting (AWL) is a Defence in Depth strategy that specifies the authorized applications for use within a computer network. There are multiple ways that users can intentionally and unintentionally download malicious software.

This can be automated by calling "%LOCALAPPDATA%\slack\Update.exe" --uninstall -s in the users context, e.g. during the logon script. If your machine hosts multiple users (e.g. a terminal server), then we recommend our machine-wide MSI which would uninstall Slack for all users automatically.

As you can see, there is a lot of content here. Microsoft Teams has become very pervasive globally. In turn, Microsoft is aware of how much guidance IT Pros need to be able to efficiently support it, including NOT installing it for all users.

With Terminal Server, a user can experience running a desktop over the internet with the Windows Remote Desktop Connection feature. They do not need to install any programs on their machine and none of the data streams across the internet. Only screen refreshes are sent over the Internet so it feels like you're running the application locally but it's all happening on the server. Printing also occurs locally, so a user can run an application over Terminal Server and have it print reports on their local printer.

With the release of Windows Server 2008 R2, many enhancements were made to the Terminal Server feature. In particular, a powerful feature called "RemoteApp" is now available (see RemoteApp and Desktop Connection from Microsoft for more details). With RemoteApp, you can "lock down" the Windows desktop to limit users to a single Windows application. Unlike a remote desktop environment, RemoteApp restricts the user from running other applications, browsing the network, etc. 2b1af7f3a8
