Description

The Unblock-SmbShareAccess cmdlet removes all of the deny access control entries (ACEs) for the trustee from the security descriptor of the Server Message Block (SMB) share.

Examples

Example 1: Remove the deny ACEs for a trustee

PS C:\>Unblock-SmbShareAccess -Name "VMFiles" -AccountName "Guest Users"
Confirm 
Are you sure you want to perform this action? 
Performing operation 'Modify' on Target 'Contoso-SO,VMFiles'. 
[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [S] Suspend  [?] Help (default is "Y"): Y 

Name                    ScopeName               AccountName             AccessControlType       AccessRight 
----                    ---------               -----------             -----------------       ----------- 
VMFiles                 Contoso-SO              Contoso\Guest           Deny                    Full

VMFiles                 Contoso-SO              Contoso\Contoso-HV1$    Allow                   Full

This command removes all of the deny ACEs for the trustee from the security descriptor of the SMB share.

Example 2: Remove the deny ACEs for a trustee without confirmation

PS C:\>Unblock-SmbShareAccess -Name "VMFiles" -AccountName "Contoso\Guest" -Force
Name                    ScopeName               AccountName             AccessControlType       AccessRight 
----                    ---------               -----------             -----------------       ----------- 
VMFiles                 Contoso-SO              Contoso\Administrator   Allow                   Full 
VMFiles                 Contoso-SO              Contoso\Contoso-HV1$    Allow                   Full

This command removes all of the deny ACEs for the trustee from the security descriptor of the SMB share without user confirmation.

Parameters

-AccountName

Specifies an array of the names of the trustees whose deny ACEs are removed from the security descriptor of the SMB share. Specify a comma-separated list to unblock multiple trustees.

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.
