How to change ownership and give full permissions to a user on a folder (VBScript)

Hi all,

Some time ago we faced an issue where a customer renamed users in their domain, but their profile folders didn't get renamed. So they wanted to automate the following process which worked for them when doing it manually: take ownership of a user's profile folder with an administrator, give full permissions to that admin on the folder, rename it, and give full permissions back to that user.

The following VBScript sample shows how to give ownership to a user on a folder, how to give full permissions to a user on a folder, and how to rename the folder. For that it will use WMI to manipulate the Security Descriptor of the folder:

 '=======================================================================
' PARAMETERS
'-----------------------------------------------------------------------
'
' Documents and settings path
strDocsSetsPath = "C:\Documents and Settings\"

' Original user name
strOriginalUserName = "OriginalNameOfUser"

' Original user domain
strOriginalDomainName = "DomainOfUser"

' Target user name
strTargetUserName = "NewNameOfUser" 


'=======================================================================
' CONSTANTS
'-----------------------------------------------------------------------
'
' Rights granted or denied to a trustee.

const FILE_APPEND_DATA =      &H000004 
const FILE_ADD_SUBDIRECTORY = &H000004
const FILE_READ_EA =          &H000008
const FILE_WRITE_EA =         &H000010
const FILE_EXECUTE =          &H000020
const FILE_TRAVERSE =         &H000020
const FILE_DELETE_CHILD =     &H000040
const FILE_READ_ATTRIBUTES =  &H000080
const FILE_WRITE_ATTRIBUTES = &H000100
const DELETE =                &H010000
