Also is there a command to kill the connection if the user is logon? Sometime there is the need to bring down the DC. If there is a command I can see who is still authenticated on active directory and kill the connection like just Novell and unix have.

Never had to cut the connection. Just reboot and the clients will be reconnected when it boots back up seemlessly. Scott Smith. Log in or Sign up to hide this advert.

In my logon script how can I determine the name of the domain controller that authenticated the user? Hey, CK. You know, one of the unwritten rules for being a Scripting Guy is that you should never do anything hard more than once a week.

Why is this an unwritten rule? Mainly because we were all too lazy to write it down. So how easy could it be to determine the name of the domain controller that authenticated the logged-on user? As easy as three lines of code:. And even if you were dreaming, well, do you really want to admit that you dream about scripting?

We begin by binding to rootDSEwhich represents the root of the Active Directory service on a domain controller.

The rootDSE object exists to provide information about a domain and a domain controller; in fact, one piece of information rootDSE provides is the value of the dnsHostName property. That might not be the most intuitive property name in the world, but dnsHostName is the name of the authenticating domain controller.

Consequently we use the Get method to retrieve the value of the dnsHostName attribute and store that value in a variable named strDC. And now, having presented our three-line script, our work for today is done.

Recordset ADOR.Describes the best practices, location, values, policy management, and security considerations for the Access this computer from the network security policy setting. The Access this computer from the network policy setting determines which users can connect to the device from the network. Users, devices, and service accounts gain or lose the Access this computer from network user right by being explicitly or implicitly added or removed from a security group that has been granted this user right.

For example, a user account or a machine account may be explicitly added to a custom security group or a built-in security group, or it may be implicitly added by Windows to a computed security group such as Domain Users, Authenticated Users, or Enterprise Domain Controllers. By default, user accounts and machine accounts are granted the Access this computer from network user right when computed groups such as Authenticated Users, and for domain controllers, the Enterprise Domain Controllers group, are defined in the default domain controllers Group Policy Object GPO.

The following table lists the actual and effective default policy values for the most recent supported versions of Windows. When modifying this user right, the following actions might cause users and services to experience network access issues:. Any change to the user rights assignment for an account becomes effective the next time the owner of the account logs on. Settings are applied in the following order through a Group Policy Object GPOwhich will overwrite settings on the local computer at the next Group Policy update:.

This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation. Users who can connect from their device to the network can access resources on target devices for which they have permission.

For example, the Access this computer from the network user right is required for users to connect to shared printers and folders. If this user right is assigned to the Everyone group, anyone in the group can read the files in those shared folders. However, if a device is upgraded and the original device includes the Everyone group as part of its defined users and groups, that group is transitioned as part of the upgrade process and is present on the device. Restrict the Access this computer from the network user right to only those users and groups who require access to the computer.

For example, if you configure this policy setting to the Administrators and Users groups, users who log on to the domain can access resources that are shared from servers in the domain if members of the Domain Users group are included in the local Users group.

Note If you are using IPsec to help secure network communications in your organization, ensure that a group that includes machine accounts is given this right.

This right is required for successful computer authentication. Assigning this right to Authenticated Users or Domain Computers meets this requirement. If you remove the Access this computer from the network user right on domain controllers for all users, no one can log on to the domain or use network resources. If you remove this user right on member servers, users cannot connect to those servers through the network.

If you have installed optional components such as ASP. It is important to verify that authorized users are assigned this user right for the devices that they need to access the network.

This setting includes the Everyone group to ensure backward compatibility. Upon Windows upgrade, after you have verified that all users and groups are correctly migrated, you should remove the Everyone group and use the Authenticated Users group instead. Group Policy Settings are applied in the following order through a Group Policy Object GPOwhich will overwrite settings on the local computer at the next Group Policy update: Local policy settings Site policy settings Domain policy settings OU policy settings When a local setting is greyed out, it indicates that a GPO currently controls that setting.

Vulnerability Users who can connect from their device to the network can access resources on target devices for which they have permission. Countermeasure Restrict the Access this computer from the network user right to only those users and groups who require access to the computer.

Potential impact If you remove the Access this computer from the network user right on domain controllers for all users, no one can log on to the domain or use network resources.

Yes No. Any additional feedback? Skip Submit.A security identifier SID is a unique value of variable length that is used to identify a security principal such as a security group in Windows operating systems.

SIDs that identify generic users or generic groups is particularly well-known. Their values remain constant across all operating systems. This information is useful for troubleshooting issues that involve security. This article describes circumstances under which the ACL editor displays a security principal SID instead of the security principal name.

When you add a domain controller that runs Windows Server or a later version to a domain, Active Directory adds the security principals in the following table. The Windows ACL editor may not display these security principles by name. This subkey also contains any capability SID that is added by first-party or third-party applications. Skip to main content.

Having checked several threads on the internet regarding this i checked the gpo applied to the DC's. I even added the seting "Deny access to this computer from the network" in user rights assignment. Enumeration of AD accounts as you have shown is not possible with null credentials with your current settings - so if this was one of your objectives, there is nothing more you need to do in this regard.

If that's the case, ensure also that Network access: Restrict anonymous access to Named Pipes and Shares is enabled. As Florian has pointed out, this is not enabled by default - so as long as your observation is accurate and you are actually using anonymous bindyou might have the default configuration settings changed.
