6.22.2.3 Using VBScript
' This code sets a users password to never expire ' See Recipe 4.12 for the code for the CalcBit function ' ------ SCRIPT CONFIGURATION ------ strUserDN = "<UserDN>"  ' e.g. cn=rallen,ou=Sales,dc=rallencorp,dc=com ' ------ END CONFIGURATION --------- intBit = 65536 strAttr = "userAccountControl" set objUser = GetObject("LDAP://" & strUserDN) intBitsOrig = objUser.Get(strAttr) intBitsCalc = CalcBit(intBitsOrig, intBit, TRUE) if intBitsOrig <> intBitsCalc then    objUser.Put strAttr, intBitsCalc    objUser.SetInfo    WScript.Echo "Changed " & strAttr & " from " & _                 intBitsOrig & " to " & intBitsCalc else    WScript.Echo "Did not need to change " & strAttr & " (" & _                 intBitsOrig & ")" end if

6.22.3 Discussion

Setting a user's password to never expire overrides any password aging policy you've defined in the domain. To disable password expiration, you need to set the bit equivalent of 65536 (i.e., 10000000000000000) in the userAccountControl attribute of the target user.
