But (there is always at least one but) deleting of the mailboxes was including automatically deleting of user accounts on domain so in other words no one could log in on the domain or their own computers connected to domain.

Exploring MSDN and Google for solutions I have learned yesterday that deletion of objects on AD is not meaning that they are deleted directly, it’s rather that they are moved to a side for a quite long time until being deleted. So as it means that they are not deleted, restore should be easy, and it was (thinking on all possible scenarios).

There is one program called ADRestore.net which you can find on this link.

On the link above you can download program and see it in action, so in the end I have succeeded to restore all accounts with help of it.

NOTE: Restoring of the objects does not mean that all of its properties and parameters will be restored with it, so you will need to review them and fix as needed, generate new passwords and so on.

So procedure would look like this:

• find wpa.dbl file and save it to some external media (usb disk, floppy, cd, etc.)
• reinstall Windows
• after reinstallation skip registration and activation
• restart pc and on boot pres F8 to enter menu where you can select safe mode
• in safe mode rename existing wpa.dbl file to wpa.dbl.backup and copy old one
• restart
• VOILA!!

So procedure is very simple and if you create your own installation cd with help of Nlite you can include this file too and skip activation after reinstallation.

Note: This file that you have saved can be used only on the PC that it comes from, on others it won’t work.
