For standard users, the only way that UAC will function well is if all applications that run on the desktop can be run without requiring administrator credentials.
In this situation, the user can perform all of the functions and run all applications as a standard user. Then, if a task needs to be performed that requires administrative access, they can get help from someone on the helpdesk or an administrator. Further information on UAC. Even though passwords are not all that attractive as a security setting, the ability to control passwords using Group Policy can't be left off of the top 5 list. Windows Server still uses Group Policy to determine the initial account policy settings, which have not changed since Windows The settings are initially configured in the Default Domain Policy, but they can be made in any GPO which is linked to the domain.
The only thing to keep in mind is that the GPO that contains the account policy settings must have the highest priority of all GPOs linked to the domain.
The settings that you can configure include those shown in Figure 5 and the settings shown in Table 1. If you want to set the new granular password policy settings, refer to the following articles on www. The Windows Server Group Policy options are impressive. With over settings, you will not get bored with the potential you have in controlling the computers in your environment. If you take advantage of the settings shown in this article, you will have a more secure desktop environment and overall network.
Your email address will not be published. Learn about the latest security threats, system optimization tricks, and the hottest new technologies in the industry. If you are familiar with concept of Kerberos in Windows Server , you may already know that once a user logs on successfully, the operating system supplies them with a security token.
That token has their privileges and group membership. The whole idea is that the user does not have to keep typing in their password every time they need to open a file or print. User Account Control extends this idea by supplying what some call a split token and other call two tokens. What ever the semantics, the idea is that to perform jobs such as checking their email or updating their spreadsheets, the Administrator relies on the lesser token, the one with minimal rights.
Suppose that same user account now needs to carry out a higher level administrative task, for example, changing a DNS record or amending a DHCP scope option; at this point they need to switch to the other full token, known as Administrator Approval Mode.
Imagine a user launching a snap-in from the MMC. The Windows Windows Server shell calls CreateProcess, which then queries the application to see whether it requires elevated privileges. If the application does not require elevated privilege the process is created through NtCreateProcess — end of story.
However, let us assume that the snap-in requires elevated privilege, in this instance CreateProcess, returns an error to ShellExecute. More than just a mere change of acronym, this indicates that UAC is part of a larger security area, which Microsoft are rapidly evolving.
Following feedback from beta testers, Microsoft fine tuned the balance between high security and ease-of-use for the UAC.
I have to say that at least on training courses, RunAs was one of the least liked features of Windows Server User Account Control makes it easier to develop good habits and work securely. In summary, User Account Control automatically gives you the best of both worlds, rely on a basic token for routine tasks and reserve the Administrative token for special security responsibilities.
This is how it works. This page gives you strategies for controlling this service. Drill down to Security Options folder. Figure B Click the image to enlarge. Editor's Picks.

Paging Zefram Cochrane: Humans have figured out how to make a warp bubble. Prompt for consent for non-Windows binaries. Default When an operation for a non-Microsoft application requires elevation of privilege, the user is prompted on the secure desktop to select either Permit or Deny.
The User Account Control: Behavior of the elevation prompt for standard users policy setting controls the behavior of the elevation prompt for standard users. The User Account Control: Detect application installations and prompt for elevation policy setting controls the behavior of application installation detection for the computer.
The User Account Control: Only elevate executables that are signed and validated policy setting enforces public key infrastructure PKI signature checks for any interactive applications that request elevation of privilege.
Enterprise administrators can control which applications are allowed to run by adding certificates to the Trusted Publishers certificate store on local computers. The User Account Control: Only elevate UIAccess applications that are installed in secure locations policy setting controls whether applications that request to run with a User Interface Accessibility UIAccess integrity level must reside in a secure location in the file system.
Secure locations are limited to the following:. Note Windows enforces a PKI signature check on any interactive application that requests to run with a UIAccess integrity level regardless of the state of this security setting. If you change this policy setting, you must restart your computer. Note If this policy setting is disabled, the Windows Security app notifies you that the overall security of the operating system has been reduced. The User Account Control: Switch to the secure desktop when prompting for elevation policy setting controls whether the elevation request prompt is displayed on the interactive user's desktop or the secure desktop.
When this policy setting is enabled, it overrides the User Account Control: Behavior of the elevation prompt for administrators in Admin Approval Mode policy setting. The following table describes the behavior of the elevation prompt for each of the administrator policy settings when the User Account Control: Switch to the secure desktop when prompting for elevation policy setting is enabled or disabled.
When this policy setting is enabled, it overrides the User Account Control: Behavior of the elevation prompt for standard users policy setting. The following table describes the behavior of the elevation prompt for each of the standard user policy settings when the User Account Control: Switch to the secure desktop when prompting for elevation policy setting is enabled or disabled.
The User Account Control: Virtualize file and registry write failures to per-user locations policy setting controls whether application write failures are redirected to defined registry and file system locations.
