After an emergency shutdown of a physical server with an Active Directory domain controller role, the BSOD with an error stop code 0x00002e2 appears on boot. The error points out that the Active Directory database (NTDS.DIT) is damaged. In this article, we will figure out how to fix the ntds.dit file and start a domain controller (in our case, it is a server running Windows Server 2019).

The Select-Object cmdlet allows you to display certain properties of an object in a PowerShell command. Select-Object can select unique objects, a specified number of objects, or objects at a specified position in an array. Also, some PowerShell cmdlets don’t display all of the object’s properties, and you must use Select-Object to display additional attributes.

By default, when connecting, OpenVPN clients receive a dynamic IP from the DHCP range that you set in the OpenVPN server configuration file (server.ovpn) server network netmask (for example, server 10.24.1.0 255.255.255.0). In some cases, you want certain OpenVPN clients to get the same static IP address every time they connect.

When you mount network drives in Windows (manually, via net use, or GPO), File Explorer shows the full UNC path to the mapped network folder as the drive name. In this example, the network shared folder \\DESKTOP-1FOH5A8\Share\Docs\Reports\2022 is mapped as drive Z:\. Displaying the network drive name as a UNC path is inconvenient for many users. In Windows, you can change the name of the mapped network drive through the registry.
