function Get-RegMultiString { <# .SYNOPSIS Retrieves an array of null-terminated strings (REG_MULTI_SZ) from local or remote computers. .DESCRIPTION Use Get-RegMultiString to retrieve an array of null-terminated strings (REG_MULTI_SZ) from local or remote computers. .PARAMETER ComputerName An array of computer names. The default is the local computer. .PARAMETER Hive The HKEY to open, from the RegistryHive enumeration. The default is 'LocalMachine'. Possible values: - ClassesRoot - CurrentUser - LocalMachine - Users - PerformanceData - CurrentConfig - DynData .PARAMETER Key The path of the registry key to open. .PARAMETER Value The name of the registry value. .PARAMETER Ping Use ping to test if the machine is available before connecting to it. If the machine is not responding to the test a warning message is output. .EXAMPLE $Key = "SYSTEM\CurrentControlSet\services\LanmanServer\Shares" Get-RegMultiString -Key $Key -Value Drivers ComputerName Hive Key Value Data ------------ ---- --- ----- ---- COMPUTER1 LocalMachine SYSTEM\CurrentControlSet\services\LanmanServer\Shares Drivers {CSCFlags=0, MaxUses=429496729... Description ----------- The command gets the flags of the Drivers system shared folder from the local computer. The name of ComputerName parameter, which is optional, is omitted. .EXAMPLE "DC1","DC2" | Get-RegString -Key $Key -Value Sysvol -Ping ComputerName Hive Key Value Data ------------ ---- --- ----- ---- DC1 LocalMachine SYSTEM\CurrentControlSet\services\LanmanServer\Shares Sysvol {CSCFlags=256, MaxUses=429496... DC2 LocalMachine SYSTEM\CurrentControlSet\services\LanmanServer\Shares Sysvol {CSCFlags=256, MaxUses=429496... Description ----------- The command gets the flags of the Sysvol system shared folder from two DC computers. When the Switch parameter Ping is specified the command issues a ping test to each computer. If the computer is not responding to the ping request a warning message is written to the console and the computer is not processed. .EXAMPLE Get-Content servers.txt | Get-RegString -Key $Key -Value Sysvol ComputerName Hive Key Value Data ------------ ---- --- ----- ---- DC1 LocalMachine SYSTEM\CurrentControlSet\services\LanmanServer\Shares Sysvol {CSCFlags=256, MaxUses=429496... DC2 LocalMachine SYSTEM\CurrentControlSet\services\LanmanServer\Shares Sysvol {CSCFlags=256, MaxUses=429496... Description ----------- The command uses the Get-Content cmdlet to get the DC names from a text file. .OUTPUTS PSFanatic.Registry.RegistryValue (PSCustomObject) .NOTES Author: Shay Levy Blog : http://blogs.microsoft.co.il/blogs/ScriptFanatic/ .LINK http://code.msdn.microsoft.com/PSRemoteRegistry .LINK Set-RegMultiString Get-RegValue Remove-RegValue Test-RegValue #> [OutputType('PSFanatic.Registry.RegistryValue')] [CmdletBinding(DefaultParameterSetName="__AllParameterSets")] param( [Parameter( Position=0, ValueFromPipeline=$true, ValueFromPipelineByPropertyName=$true, HelpMessage="An array of computer names.
