Dear all,
AD Infra:
Root AD x 2 (Windows Server 2008 R2)
Child AD x 2 (Windows Server 2008 R2)
Issue:
Old or legacy domain account cannot login to domain computer.
Will prompt password is not correct even confirmed it is correct.
Have reset the password but the error throw the same.
Newly created domain account for the last 1month can login without issue.
Latest activities being performed:
FFL and DFL raised from W2003 to W2008.
Adprep command for Windows Server 2019 planned upgrade.
Is there anything need to be checked?
Thanks.
