Constrained Language Mode issue

My objective is to remove all ‘old’ account names on Profile shares since the domain is going away. These shares reside on a clustered file share environment and I need to run through each profile to remove any account with the ‘mmsasp’ domain in it.

The language mode is constrained language mode and I can 't seem to find a way around it.



$Profiles = Get-ChildItem D:\Profiles foreach ($Profile in $Profiles){

$acl = get-acl $Profile.FullName
$rules = $acl.Access | Where-Object {$_.identityreference -like “mmsasp”}

foreach ($rule in $rules ){
write-host $Profile.FullName -ForegroundColor Yellow

set-acl -Path $Profile.FullName -AclObject $acl

Example OutPut

D:\Profiles\easystreet FileSystemRights : FullControl AccessControlType : Allow IdentityReference : MMSASP\Domain Admins IsInherited : True InheritanceFlags : ContainerInherit, ObjectInherit PropagationFlags : None

Cannot invoke method. Method invocation is supported only on core types in this language mode.

Yes this is constrained language mode and this action is not supported there. You can workaround this by calling the script in a new exe without constrained language mode.

PowerShell.exe -f c:\yourscript.ps1
