You want to prevent a user’s password from expiring.


Using a graphical user interface

  1. Open the ADUC snap-in.
  2. In the left pane, right-click on the domain and select Find.
  3. Select the appropriate domain beside In.
  4. Beside Name, type the name of the user you want to modify and click Find Now.
  5. In the Search Results window, double-click on the user.
  6. Click the Account tab.
  7. Under Account options, check the box beside “Password never expires.”
  8. Click OK.

Using a command-line interface

> dsmod user “<UserDN>” -pwdneverexpires yes

Using VBScript

‘ This code sets a

users password to never expire


strUserDN = “<UserDN>” ‘ e.g. cn=rallen,ou=Sales,dc=rallencorp,dc=com


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


WScript.Echo “Changed ” & strAttr & ” from ” & _

intBitsOrig & ” to ” & intBitsCalc


WScript.Echo “Did not need to change ” & strAttr & ” (” & _

intBitsOrig & “)”

end if


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.
