    Afternoon All,

    Got an odd bug here, wondered if anyone had had anything similar in the past - it's more of an ongoing annoyance as it doesn't really stop them working.

    Server/Domain:

    Windows Server 2008 R2 DC x2, Domain @ Windows Server 2003 Functional Level

    The Situation:

    We have a client with multiple physical locations, these are mapped to OU's at the top level, ie

    Domain.local

    -> Location 1

    -> Location 2

    -> Location 3

    • A Users OU under Location 3 has a GP linked that sets it's password policy, this has a Minimum Age value set at 1 day amongst other settings.
    • Location 1 / 2 do not have this policy linked in any OU's, and it is not linked at the domain level.
    • The Default Domain Policy only includes settings for: Minimum Password Length ( 8 ), Complexity Requirements (Enabled) and Reversible Encryption (Disabled)

    The Problem:

    Users anywhere in the domain, irrespective if their OU, are being limited by the minimum 1 day password age and cannot reset until this time has elapsed.

    Tests:

    I have done a GP model based on a user affected last Friday - output is that he should not have been limited by the 1 day, it does not show in the output, yet he could not change his password until he retried on Monday.
    I have confirmed on the Location 1 -> Users OU that the GP Inheritance only shows the Default Domain Policy and an old SBS policy, non of which set the Minimum Password Age value.

    Question:

    Any ideas why this may be happening or a solution to rectify?

    Odd. Since you're running at 2K3 functional level, you can only have one password policy in a domain - set at the domain level. Anything you set anywhere else in the domain (with the exception, of course, of child domains) is worthless - so straightaway the extraneous GPOs in OU 3 should NOT be taking effect. Are you sure that the minimum age isn't set in the default domain policy? Don't forget that password policies are computer-based, not user-based.

    Maybe you should dial up userenv logging for some better testing (gpresult is a useful tool for quick and easy fixes, but a PITA when looking for more detail). Google 'usernev logging' and you'll find a Technet article on how to set the level a bit higher (though be prepared for some yawns whilst you trawl through the subsequent logs looking for the relevant information :biggrin)

    Didn't know that about the password policy limit, cheers.

    Yes can confirm that the default policy has only the three items stated, linked at the top domain level. It's quite a basic setup to be truthful so there isn't much in that default policy.

    I'll take a look in to that.
