We had a problem yesterday where the users were missing from AD (automatically deleted)
We managed to restore the deleted users and set them back up again.
Today the user objects are missing again from ADUC.
Naturally we know how to restore them, but it looks like this is just going to keep happening.
Once the users dont logout of their PC their session remains active, but once they log out they cant log back in as they dont exist.
The only think we noticed is we have some TS user objects (that dont have an exchange mailbox) that are not getting deleted.
We have no idea why this is happening and need to find the root cause urgently.
Any help appreciated.
