Description

The Set-SmbServerCertificateMapping cmdlet modifies a certificate's association to the SMB server for SMB over QUIC. For more information, see SMB over QUIC.

Note

• If the RequireClientAuthentication parameter is set to $true and SkipClientCertificateAccessCheck is set to $false, the server will perform both client certificate validation and access control checks.

• If the RequireClientAuthentication parameter is set to $true and SkipClientCertificateAccessCheck is also set to $true, the server will perform client certificate validation but no access control checks.

Examples

Example 1: Enable Named Pipes for the SMB over QUIC endpoint

This command enables Named Pipes for the SMB over QUIC endpoint, overriding the default behavior where Named Pipes are disabled for increased security.

$params = @{
    Name = "2022-ae-02.corp.contoso.com"
    Thumbprint = "88032B3551FAF7DE26EFFFF814AA086E3DBD2A4F"
    StoreName = "My"
    Flags = "AllowNamedPipe"
}
Set-SmbServerCertificateMapping @params

Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-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.

Type:	CimSession[]
Aliases:	Session
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:	SwitchParameter
Aliases:	cf
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Flags

Specifies if Named Pipes are enabled for SMB over QUIC. The acceptable values for this parameter are:

• None: Remove all flags.
• AllowNamedPipe: Enable use of named pipes in SMB over QUIC connections for this mapping (off by default, overrides the value of RestrictNamedPipeAccessOverQuic).
• DefaultCert: Not used.

Type:	Flags
Accepted values:	None, AllowNamedPipe, DefaultCert
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-InputObject

Specifies the input object that's used in a pipeline command.

Type:	CimInstance[]
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-Name

Specifies a fully-qualified DNS name or NetBIOS name that must match the certificate's subject name or an entry in the certificate's subject alternative names.

Type:	String[]
Position:	1
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-PassThru

Returns an object representing the item with which you're working. By default, this cmdlet doesn't generate any output.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-RequireClientAuthentication

Specifies whether client authentication is required for connections to the server. When this parameter is set to $true, clients must present a valid certificate to connect to the server. When it is set to $false, clients can connect without presenting a certificate.

Type:	Boolean
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-SkipClientCertificateAccessCheck

Specifies whether the server should skip the check for client certificate access when a client connects. This parameter only applies when the server certificate mapping RequireClientAuthentication value is $true. When this parameter is set to $true, the server will not perform the access control checks based on the client certificates. This can be useful in scenarios where the server is acting as a gateway or proxy and client certificate validation is sufficient.

However, it can also increase the risk of security breaches. When this parameter is set to $false, the server will perform the access control checks based on the client certificates in addition to the client certificate validation before allowing the client to connect.

Type:	Boolean
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-StoreName

Specifies the path to the certificate store for the certificate. The recommended value is "My" for the local machine personal store.

Type:	String
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-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.

Type:	Int32
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Thumbprint

Specifies the thumbprint value of the certificate.

Type:	String
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet isn't run.

Type:	SwitchParameter
Aliases:	wi
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False
