Microsoft NetAdapter reference: Disables the selected checksum offloads on the network adapter. The syntax and selected example below are adapted from the pinned Windows Server 2025 reference. Module availability, target configuration and delegated permissions determine whether it can run in your environment. Documentation and parameter text: Microsoft, CC BY 4.0; formatting adapted by Cmdlet World. No execution testing is claimed.
Use an account with the target resource permissions documented for Disable-NetAdapterChecksumOffload. Modifying administrative cmdlets may require elevation or delegated administration. This catalog does not assert that ordinary users can execute the command.

Parameters
-AsJob
Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs.
-CimSession
Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.
-Confirm
Prompts you for confirmation before running the cmdlet.
-IncludeHidden
Indicates that the cmdlet includes both visible and hidden network adapters in the operation. By default only visible network adapters are included. If a wildcard character is used in identifying a network adapter and this parameter has been specified, then the wildcard string is matched against both hidden and visible network adapters.
-InputObject (required)
Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet.
-InterfaceDescription (required)
Specifies an array of network adapter interface descriptions. For a physical network adapter this is typically the name of the vendor of the network adapter followed by a part number and description, such as Contoso 12345 Gigabit Network Device.
-IpIPv4
Indicates that the cmdlet disables IPv4 checksum offloading.
-Name (required)
Specifies an array of network adapter names.
-NoRestart
Indicates that the cmdlet does not restart the network adapter after completing the operation. Many advanced properties require restarting the network adapter before the new settings take effect.
-PassThru
Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
-TcpIPv4
Indicates that the cmdlet disables TCP IPv4 checksum offloading.
-TcpIPv6
Indicates that the cmdlet disables TCP IPv6 checksum offloading.
-ThrottleLimit
Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.
-UdpIPv4
Indicates that the cmdlet disables UDP IPv4 checksum offloading.
-UdpIPv6
Indicates that the cmdlet disables UDP IPv6 checksum offloading.
-WhatIf
Shows what would happen if the cmdlet runs. The cmdlet is not run.
Prerequisites
Windows with the NetAdapter module and the Windows feature or management tools that provide it. Confirm target connectivity and version compatibility using the linked Microsoft reference.
Security considerations
This cmdlet changes system state. Review every target and parameter in the official reference, test outside production, and prepare an appropriate backup or rollback. Do not execute the example automatically.
Examples
Example 1: Disable TCP/IPv6 checksum offload on all network adapters then restart them
This command disables TCP/IPv6 checksum offload on all network adapters and restarts the network adapters. Source: Microsoft, CC BY 4.0; transcript prompt/output removed. This example was not executed.
