PowerShell: Grant Domain Admins Access to Directories

Snippet:

# Messing around
$shareDrives=@("E","F","G","I","J","N",'O','Q','R','S','T','U','V','W','Z','Y');
$subdomain=(net config workstation) -match 'Workstation domain\s+\S+$' -replace '.+?(\S+)$','$1';
$domainadmins="$subdomain`\Domain Admins"; 
$shareDrives | %{"Add-NTFSAccess –Path '$_`:\' –Account $domainadmins –AccessRights Full -ErrorAction SilentlyContinue";}

# The real deal (will take a long time to process)
# Limitations: a) it will not modify ACLs of root volumes b) will not modify items where "SYSTEM" or "Administrators" have no access
$shareDrives=@("E","F","G","I","J","N",'O','Q','R','S','T','U','V','W','Z','Y');
$subdomain=(net config workstation) -match 'Workstation domain\s+\S+$' -replace '.+?(\S+)$','$1';
$domainadmins="$subdomain`\Domain Admins"; 
$shareDrives | %{Add-NTFSAccess –Path "$_`:\Shares" –Account $domainadmins –AccessRights Full -ErrorAction SilentlyContinue;}
