UF_PASSWD_NOTREQD Flag Set in DC's userAccountControl

Discussion in 'Active Directory' started by Infrastructure Guy, Jun 8, 2007.

  1. DCDIAG reveals that someone set the userAccountControl on 1 of my 6 DCs to
    0x82020 instead of leaving it at 0x82000. This sets the UF_PASSWD_NOTREQD

    I just inherited this domain and see no reason not to set the
    userAccountControl back to 0x82000. I see nothing special running on this
    DC. Does anyone know any reason not to set it back?

    Does anyone know of any 3rd party software that requires the

    I do not know of any software that would require this. Furthermore, I would
    be very suspicions of any that did!

    I would set up a lab environment and play with this before doing so in a
    production environment. You do have six Domain Controllers (I am going to
    assume that there are multiple Sites involved....). While there should be
    no issues with doing this I must say that I have never done this (set to
    0x82020 and then switched it to 0x82020). I would hate to find out the hard

    Hi Cary,

    What I think may be happening is the one entry on the one DC that is
    different is possibly the original DC created in the domain. The reason I
    believe this is when the first DC is created, it will need to allow the
    admin account to have a NULL password (blank). But once other DCs are added,
    the Default Domain Policy forces them to not allow a NULL password, well at
    least with Windows 2003.

    Maybe someone else can verify this.
