+# Block-SmbClientAccessToServer
+
+## SYNOPSIS
+Blocks SMB client access to a specified server.
+
+## SYNTAX
+
+### Query
+
+```
+Block-SmbClientAccessToServer [-Name] <String[]> -IdentifierType <IdentifierType>
+ -Identifier <String> [-Description <String>] [-Force] [-CimSession <CimSession[]>]
+ [-ThrottleLimit <Int32>] [-AsJob] [-WhatIf] [-Confirm] [<CommonParameters>]
+```
+
+### InputObject
+
+```
+Block-SmbClientAccessToServer -InputObject <CimInstance[]> -IdentifierType <IdentifierType>
+ -Identifier <String> [-Description <String>] [-Force] [-CimSession <CimSession[]>]
+ [-ThrottleLimit <Int32>] [-AsJob] [-WhatIf] [-Confirm] [<CommonParameters>]
+```
+
+## DESCRIPTION
+
+The `Block-SmbClientAccessToServer` cmdlet is used to prevent SMB clients from accessing a
+specified server when using SMB over QUIC client access control. When you run this cmdlet, all SMB
+client connections to the specified server will be terminated, and no new connections will be
+allowed until the block is lifted. To unblock access to the server, use the
+`Unblock-SmbClientAccessToServer` cmdlet.
+
+## EXAMPLES
+
+### Example 1: Block SMB client access to a server
+
+```powershell
+$params = @{
+    Name = "Server01"
+    IdentifierType = "ISSUER"
+    Identifier = "CN=MyCertificateIssuer"
+    Force = $true
+}
+Block-SmbClientAccessToServer @params
+```
+
+This command blocks SMB client access to a server named `Server01` for the based on the client's
+certificate. This command runs without prompting for confirmation as the **Force** parameter is set
+to `$true`.
+
+## PARAMETERS
+
+### -AsJob
+
+Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to
+complete.
+
+```yaml
+Type: SwitchParameter
+Parameter Sets: (All)
+Aliases:
+
+Required: False
+Position: Named
+Default value: None
+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](/powershell/module/cimcmdlets/new-cimsession) or
+[Get-CimSession](/powershell/module/cimcmdlets/get-cimsession) cmdlet. The default is the
+current session on the local computer.
+
+```yaml
+Type: CimSession[]
+Parameter Sets: (All)
+Aliases: Session
+
+Required: False
+Position: Named
+Default value: None
+Accept pipeline input: False
+Accept wildcard characters: False
+```
+
+### -Description
+
+Used to provide a description of the rule being added to the server's firewall when you use the
+`Block-SmbClientAccessToServer` cmdlet. This can be useful if you need to keep track of why SMB
+client access to a server has been blocked, or if you need to provide additional information about
+the block for documentation purposes.
+
+```yaml
+Type: String
+Parameter Sets: (All)
+Aliases:
+
+Required: False
+Position: Named
+Default value: None
+Accept pipeline input: False
+Accept wildcard characters: False
+```
+
+### -Force
+
+Forces the command to run without asking for user confirmation.
+
+```yaml
+Type: SwitchParameter
+Parameter Sets: (All)
+Aliases:
+
+Required: False
+Position: Named
+Default value: None
+Accept pipeline input: False
+Accept wildcard characters: False
+```
+
+### -Identifier
+
+Specifies the identity of the client that is being granted access to the SMB server. This parameter
+takes a string value that represents the identity of the client. The format of the string value
+will depend on the **IdentifierType** parameter that you're using.
+
+```yaml
+Type: String
+Parameter Sets: (All)
+Aliases:
+
+Required: True
+Position: Named
+Default value: None
+Accept pipeline input: False
+Accept wildcard characters: False
+```
+
+### -IdentifierType
+
+Specifies the type of identifier that you're using to identify a client. The valid values for the
+**IdentifierType** parameter are:
+
+- SHA256
+- ISSUER
+
+If you're using the `SHA256` identifier type, you're specifying a hash value that uniquely
+identifies the client. If you're using the `ISSUER` identifier type, you're specifying the issuer
+of the client's certificate.
+
+```yaml
+Type: IdentifierType
+Parameter Sets: (All)
+Aliases:
+Accepted values: SHA256, ISSUER
+
+Required: True
+Position: Named
+Default value: None
+Accept pipeline input: False
+Accept wildcard characters: False
+```
+
+### -InputObject
+
+Specifies the input object that's used in a pipeline command.
+
+```yaml
+Type: CimInstance[]
+Parameter Sets: InputObject
+Aliases:
+
+Required: True
+Position: Named
+Default value: None
+Accept pipeline input: True (ByValue)
+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.
+
+```yaml
+Type: String[]
+Parameter Sets: Query
+Aliases:
+
+Required: True
+Position: 1
+Default value: None
+Accept pipeline input: True (ByPropertyName)
+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.
+
+```yaml
+Type: Int32
+Parameter Sets: (All)
+Aliases:
+
+Required: False
+Position: Named
+Default value: None
+Accept pipeline input: False
+Accept wildcard characters: False
+```
+
+### -Confirm
+
+Prompts you for confirmation before running the cmdlet.
+
+```yaml
+Type: SwitchParameter
+Parameter Sets: (All)
+Aliases: cf
+
+Required: False
+Position: Named
+Default value: False
+Accept pipeline input: False
+Accept wildcard characters: False
+```
+
+### -WhatIf
+
+Shows what would happen if the cmdlet runs. The cmdlet isn't run.
+
+```yaml
+Type: SwitchParameter
+Parameter Sets: (All)
+Aliases: wi
+
+Required: False
+Position: Named
+Default value: False
+Accept pipeline input: False
+Accept wildcard characters: False
+```
+
+### CommonParameters
+
+This cmdlet supports the common parameters: -Debug, -ErrorAction, -ErrorVariable,
+-InformationAction, -InformationVariable, -OutVariable, -OutBuffer, -PipelineVariable, -Verbose,
+-WarningAction, and -WarningVariable. For more information, see
+[about_CommonParameters](/powershell/module/microsoft.powershell.core/about/about_commonparameters).
