    Hi,
    I've made a test lab for a in-place migration to AD, using a NT4 BDC box
    then isolated from the production network . Upgraded to W2003 and AD. Test
    logon a member server (W2003 box) with sucess.
    Problem: When i put it back again the W2003 member server in the NT domain
    (production), in system event show the following message : event id 5791,
    "The domain of this computer, XPTO has been downgraded from Windows 2000 or
    newer to Windows NT4 or older.... ".

    Any help would be appreciated
    Thanks

  2. Hi,

    One of the main problems with this scenario is that once a the Win 2003
    memeber server finds a server willing to authenticate them using Kerberos
    (as a W2K or 2003
    DC would), it will never go back to NTLM. Basically, once it finds a
    Windows 2000 or 2003 DC, it will always need to authenticate with a 2000 or
    2003 DC. Therefore, I'd like to suggest you upgrade the domain to AD.

    Best regards,
