Microsoft NFS reference: Modifies configuration settings for an identity mapping store. 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 Set-NfsMappingStore. Modifying administrative cmdlets may require elevation or delegated administration. This catalog does not assert that ordinary users can execute the command.

Parameters
-ADDomainName
Specifies the Active Directory domain name that an NFS server uses as an identity mapping store.
-AsJob
Indicates that this cmdlet runs the command as a background job on a remote computer. Use this parameter to run commands that take an extensive time to finish. When you use the *AsJob* parameter, the command returns an object that represents the job, and then displays the command prompt. You can continue to work in the session while the job finishes. To manage the job, use the Job cmdlets. To get the job results, use the Receive-Job cmdlet. The *AsJob* parameter resembles using the Invoke-Command cmdlet to run a Start-Job command remotely. However, with *AsJob*, the job is created on the local computer, even though the job runs on a remote computer, and the results of the remote job are automatically returned to the local computer. For more information about Windows PowerShell background jobs, see about_Jobs and about_Remote_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.
-EnableADLookup
Sets Active Directory Domain Services (AD DS) as the mapping store on an NFS server. If *EnableADLookup* is enabled and *ADDomainName* is not explicitly configured, then the default domain (that is, the domain to which the NFS server is joined) is used as a mapping store.
-EnableLdapLookup
Sets an LDAP server or an Active Directory Lightweight Directory Services (AD LDS) server as the mapping store on an NFS server.
-EnableUNMLookup
Sets a User Name Mapping (UNM) server as the mapping store on an NFS server.
-InputObject
Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet.
-LdapNamingContext
Specifies an LDAP naming context that an NFS server uses when it performs LDAP queries.
-LdapServer
Specifies an LDAP server name or AD LDS server name that stores identity mapping. This information is used to get identity mapping information when LDAP lookup is enabled by using the *LdapLookup* parameter.
-PassThru
Returns an object that represents the item with which you are working. By default, this cmdlet does not generate any output.
-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.
-UNMServer
Specifies a UNM server. When UNM lookup is enabled by using the *EnableUNMLookup* parameter, this information is used to get identity mapping information.
-WhatIf
Shows what would happen if the cmdlet runs. The cmdlet is not run.
Prerequisites
Windows with the NFS 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.
This command enables an AD DS store on a local NFS server and sets the AD DS store mapping store to Contoso.com. Source: Microsoft, CC BY 4.0; transcript prompt/output removed. This example was not executed.
