Hello,
I have a Windows AD environment running on Windows 2008 servers. I created a user account, then deleted it, then re-added it all within about 15 minutes. When I try to log in it says "no mapping between account names and security IDs was done". I am sure it is because remnants from the old account exists. Can you please point in the right direction to rectify this? Thanks in advance!
If so you should check the event Logs for any NTDS or other replication errors. There could be a replication issue.
DCDIAG, NETDIAG and REPADMIN are all tools that can be used to check the current status of your Active Directory.
If you find errors (Failed) in the report then you need to investigate them.
