GetLaunchSecurityDescriptor - powershell.one

Gets the security descriptor that controls who is allowed to launch a DCOM application.

Example

Do not run below example code just to see what happens next. Many methods seriously affect your system. Always make sure you actually understand what the method and the code do.

# select the instance(s) for which you want to invoke the method
# you can use "Get-CimInstance -Query (ADD FILTER CLAUSE HERE!)" to safely play with filter clauses
# if you want to apply the method to ALL instances, remove "Where...." clause altogether.
$query = 'Select * From Win32_DCOMApplicationSetting Where (ADD FILTER CLAUSE HERE!)'
Invoke-CimMethod -Query $query -Namespace Root/CIMV2 -MethodName GetLaunchSecurityDescriptor |
Add-Member -MemberType ScriptProperty -Name ReturnValueFriendly -Passthru -Value {
  switch ([int]$this.ReturnValue)
  {
        0        {'Success'}
        default  {'Unknown Error '}
    }
}

To run this method on one or more remote systems, use New-CimSession:

$ComputerName = 'server12','server14'  # adjust to your server names
$Credential   = Get-Credential         # submit a user account with proper permissions



$session = New-CimSession -ComputerName $ComputerName -Credential $Credential

# select the instance(s) for which you want to invoke the method
# you can use "Get-CimInstance -Query (ADD FILTER CLAUSE HERE!)" to safely play with filter clauses
$query = 'Select * From Win32_DCOMApplicationSetting Where (ADD FILTER CLAUSE HERE!)'
Invoke-CimMethod -Query $query -Namespace Root/CIMV2 -MethodName GetLaunchSecurityDescriptor -CimSession $session |
Add-Member -MemberType ScriptProperty -Name ReturnValueFriendly -Passthru -Value {
  switch ([int]$this.ReturnValue)
  {
        0        {'Success'}
        default  {'Unknown Error '}
    }
}
