The RegEx escape character is \ so that is why the regular expression needed for the parameter is 'BUILTIN\\Administrator' .EXAMPLE Export-Permission.ps1 -TargetPath C:\Test -ExcludeAccount @( 'BUILTIN\\Administrators', 'BUILTIN\\Administrator', 'CREATOR OWNER', 'NT AUTHORITY\\SYSTEM' ) Generate reports on the NTFS permissions for the folder C:\Test and all subfolders Exclude from the HTML report: - The built-in Administrator account - The built-in Administrators group and its members (unless they appear elsewhere in the permissions) - The CREATOR OWNER security principal - The computer account (NT AUTHORITY\SYSTEM) Note: CREATOR OWNER will still be reported as an alarm in the PRTG XML output .EXAMPLE Export-Permission.ps1 -TargetPath C:\Test -ExcludeEmptyGroups Generate reports on the NTFS permissions for the folder C:\Test and all subfolders Exclude empty groups from the HTML report (leaving accounts only) .EXAMPLE Export-Permission.ps1 -TargetPath C:\Test -IgnoreDomain 'CONTOSO' Generate reports on the NTFS permissions for the folder C:\Test and all subfolders Remove the CONTOSO domain prefix from associated accounts and groups .EXAMPLE Export-Permission.ps1 -TargetPath C:\Test -IgnoreDomain 'CONTOSO1','CONTOSO2' Generate reports on the NTFS permissions for the folder C:\Test and all subfolders Remove the CONTOSO1\ and CONTOSO2\ domain prefixes from associated accounts and groups Across the two domains, accounts with the same samAccountNames will be considered equivalent Across the two domains, groups with the same Names will be considered equivalent .EXAMPLE Export-Permission.ps1 -TargetPath C:\Test -LogDir C:\Logs Generate reports on the NTFS permissions for the folder C:\Test and all subfolders Redirect logs and output files to C:\Logs instead of the default location in AppData .EXAMPLE Export-Permission.ps1 -TargetPath C:\Test -LevelsOfSubfolders 0 Generate reports on the NTFS permissions for the folder C:\Test only (no subfolders) .EXAMPLE Export-Permission.ps1 -TargetPath C:\Test -LevelsOfSubfolders 2 Generate reports on the NTFS permissions for the folder C:\Test Only include subfolders to a maximum of 2 levels deep (C:\Test\Level1\Level2) .EXAMPLE Export-Permission.ps1 -TargetPath C:\Test -Title 'New Custom Report Title' Generate reports on the NTFS permissions for the folder C:\Test and all subfolders Change the title of the HTML report to 'New Custom Report Title' .EXAMPLE Export-Permission.ps1 -TargetPath '\\ad.contoso.com\DfsNamespace\DfsFolderWithTarget' The target path is a DFS folder with folder targets Generate reports on the NTFS permissions for the DFS folder targets associated with this path .EXAMPLE Export-Permission.ps1 -TargetPath '\\ad.contoso.com\DfsNamespace\DfsFolderWithoutTarget\DfsSubfolderWithoutTarget\DfsSubfolderWithTarget' The target path is a DFS subfolder with folder targets Generate reports on the NTFS permissions for the DFS folder targets associated with this path .EXAMPLE Export-Permission.ps1 -TargetPath '\\ad.contoso.com\DfsNamespace\DfsFolderWithoutTarget\DfsSubfolderWithoutTarget\DfsSubfolderWithTarget\Subfolder' The target path is a subfolder of a DFS subfolder with folder targets Generate reports on the NTFS permissions for the DFS folder targets associated with this path .EXAMPLE Export-Permission.ps1 -TargetPath '\\ad.contoso.com\' This is an edge case that is not currently supported The target path is the root of an AD domain Generate reports on the NTFS permissions for ? Invalid/fail param validation? .EXAMPLE Export-Permission.ps1 -TargetPath '\\computer.ad.contoso.com\' This is an edge case that is not currently supported The target path is the root of a server Generate reports on the NTFS permissions for ? Invalid/fail param validation? .EXAMPLE Export-Permission.ps1 -TargetPath '\\ad.contoso.com\DfsNamespace' This is an edge case that is not currently supported The target path is a DFS namespace Generate reports on the NTFS permissions for the folder on the DFS namespace server associated with this path Add a warning that they are permissions from the DFS namespace server and could be confusing .EXAMPLE Export-Permission.ps1 -TargetPath '\\ad.contoso.com\DfsNamespace\DfsFolderWithoutTarget' This is an edge case that is not currently supported. The target path is a DFS folder without a folder target Generate reports on the NTFS permissions for the folder on the DFS namespace server associated with this path Add a warning that they are permissions from the DFS namespace server and could be confusing .EXAMPLE Export-Permission.ps1 -TargetPath '\\ad.contoso.com\DfsNamespace\DfsFolderWithoutTarget\DfsSubfolderWithoutTarget' This is an edge case that is not currently supported.
