hi I want to write a script that run after user (limit or administrator) change or reset account password!

Whether these are local accounts or accounts in Active Directory, there is nothing that can trigger a script to run when the user changes a password. The only possibility would be a scheduled task that runs a script periodically looking for recently changed passwords. For domain users, the script would check the value of the pwdLastSet attribute for all users to see if it corresponds to a date since the last time the script ran. If the accounts are local, the script would check the passwordAge property. Assuming an Active Directory domain, a VBScript program could use ADO to query AD for all users whose password has changed since a given date. See this link for details: http://www.rlmueller.net/ADOSearchTips.htm The filter would be similar to the example in the link, which is: strFilter = "(&(objectCategory=person)(objectClass=user)" _ & "(pwdLastSet>=127204308000000000))" except the value would be calculated to correspond to date in the recent past. If the scheduled task runs every 2 hours, the value would correspond to a time 2 hours in the past. The page linked above has a link to VBScript code that converts any date/time into the corresponding 64-bit value for the filter. As you can see, this is not an easy task. Richard MuellerMVP ADSI
