Resetting computer accounts in Windows

Summary

For each Windows 2000 or Windows XP workstation or server that is a member of a domain, there is a discrete communication channel, known as the security channel, with a domain controller.

The security channel’s password is stored along with the computer account on all domain controllers. For Windows 2000 or Windows XP, the default computer account password change period is every 30 days. If, for some reason, the computer account’s password and the LSA secret are not synchronized, the Netlogon service logs one or both of the following error messages:

NETLOGON Event ID 5723:
The session setup from the computer DOMAINMEMBER failed to authenticate. The name of the account referenced in the security database is DOMAINMEMBER$.
The following error occurred:
Access is denied.

NETLOGON Event ID 3210:
Failed to authenticate with \\DOMAINDC, a Windows NT domain controller for domain DOMAIN.

The Netlogon service on the domain controller logs the following error message when the password is not synchronized:

NETLOGON Event ID 5722:
The session setup from the computer ComputerName failed to authenticate. The name of the account referenced in the security database is AccountName$.
The following error occurred:
Access is denied.

This article describes four ways of resetting computer accounts in Windows 2000 or Windows XP. These methods are as follows:

Using the Netdom.exe command-line tool

Using the Nltest.exe command-line tool

Note The Netdom.exe and Nltest.exe tools are located on the Windows Server CD-ROM in the Support\Tools folder. To install these tools, run Setup.exe or extract the files from the Support.cab file.

Using the Active Directory Users and Computers Microsoft Management Console (MMC)

Using a Microsoft Visual Basic script

These tools allow for remote and non-remote administration. Netdom.exe and Nltest.exe are command-line tools that reset a successfully established security channel. You cannot use these tools when the security channel is broken, and communication is not working correctly.

More Information

Netdom.exe

For each member, there is a discrete communication channel (the security channel) with a domain controller. The security channel is used by the Netlogon service on the member and on the domain controller to communicate. Netdom makes it possible to reset the security channel of the member. You can reset the member security channel by using the following command:

netdom reset ‘machinename’ /domain:’domainname
where ‘machinename’ = the local computer name and ‘domainname’ = the domain where the computer/machine account is stored.

Suppose you have a domain member named DOMAINMEMBER in a domain called MYDOMAIN. You can reset the member security channel by using the following command:

netdom reset domainmember /domain:mydomain
You can run this command on the member DOMAINMEMBER or on any other member or domain controller of the domain, provided that you are logged on with an account that has administrator access to DOMAINMEMBER.

Nltest.exe

Nltest.exe can be used to test the trust relationship between a computer running Windows 2000 or Windows XP that is a member of a domain and a domain controller on which its machine account resides.

Usage: nltest [/OPTIONS]

/SC_QUERY: DomainName — Query security channel for domain on ServerName

/SC_VERIFY: DomainName — Verifies the security channel in the specified domain for a local or remote workstation, server, or domain controller.

Flags: 30 HAS_IP HAS_TIMESERV
Trusted DC Name \\server.windows2000.com
Trusted DC Connection Status Status = 0 0x0 NERR_Success
The command completed successfully

Active Directory Users and Computers (DSA)

With Windows 2000 or Windows XP, you can also reset the machine account from within the graphical user interface (GUI). In the Active Directory Users and Computers MMC (DSA), you can right-click the computer object in the Computers or appropriate container and then click Reset Account. This resets the machine account. Resetting the password for domain controllers using this method is not allowed. Resetting a computer account breaks that computer’s connection to the domain and requires it to rejoin the domain.

Note This will prevent an established computer from connecting to the domain and should only be used for a computer that has just been rebuilt.

Microsoft Visual Basic script

You can use a script to reset the machine account. You need to connect to the computer account using the IADsUser interface. You can then use the SetPassword method to set the password to an initial value. The initial password of a computer is always «computername$».

The following sample scripts may not work in all environments and should be tested before implementation. The first example is for Windows NT 4.0 computer accounts and the second is for Windows 2000 or Windows XP computer accounts.

How to find your PC’s model number on Windows 10

Source: Windows Central

On Windows 10, knowing the model number of your computer can be useful in many scenarios. For instance, when you have to upgrade a component (such as memory, hard drive, display, and power supply), the model number can simplify the search to obtain a compatible replacement. If you have to troubleshoot a problem, and you need to contact technical support. Or it can also come in handy to properly inventory the device.

Although a lot of manufactures usually affix a sticker and provide tools to find this information on your laptop or desktop, Windows 10 includes at least three ways to find the model number as well as serial number (also known as «service tag») of your computer using System Information, PowerShell, and Command Prompt.

In this Windows 10 guide, we will walk you through the steps to find out the model number of your device, whether it’s from Dell, HP, Acer, Lenovo, or from another brand.

How to check PC model with System Information

To find the computer model number with System Information, use these steps:

1. Open Start.
2. Search for System Information and click the top result to open the app.
3. Click on System Summary.

Confirm the model number of your device under the «System Model» field.

Once you complete the steps, you will have a clear understanding of the device model you use.

How to check PC model with PowerShell

To determine your laptop or desktop model number with PowerShell, use these steps:

1. Open Start.
2. Search for PowerShell and click the top result to open the console.

Type the following command to check the device model and the serial number and press Enter:

Get-CimInstance -ClassName Win32_ComputerSystem

Source: Windows Central

(Optional) Type the following command to check the model and serial number and press Enter:

Get-CimInstance -ClassName Win32_bios

Source: Windows Central

Confirm the model as well as serial number of your laptop or desktop PC.

After you complete the steps, the PowerShell commands will reveal the model number and the device’s serial number.

How to check PC model with Command Prompt

To figure out your computer model number with Command Prompt, use these steps:

1. Open Start.
2. Search for Command Prompt and click the top result to open the console.

Type the following command to get the desktop or laptop model and press Enter:

wmic csproduct get name

Source: Windows Central

(Optional) Type the following command to view the model and serial number and press Enter:

wmic csproduct get name, identifyingnumber

Source: Windows Central

Confirm the device model and serial number.

Once you complete the steps, the commands will display the model number and the serial number of your desktop, laptop, or tablet running Windows 10.

We are focusing these instructions on Windows 10, but you can also use these steps on Windows 8.1. On Windows 7, only the System Information and Command Prompts steps will work.
