Which Linux command can be used to log into a remote Microsoft Windows server using RDP?

The command that can be used to log into a remote Microsoft Windows server using RDP (Remote Desktop Protocol) is rdesktop. This tool is specifically designed to connect to Windows machines leveraging the RDP protocol, allowing users to manage and interact with Windows systems as if they were sitting right in front of them.

Rdesktop provides a graphical interface, enabling a seamless connection experience, similar to what you would expect from a native Windows Remote Desktop client. This makes it an effective choice for Linux users who need to access Windows resources in a mixed environment.

The other options do not support RDP. For example, rlogin is used for remote login sessions to Unix-like systems, while SSH (Secure Shell) is primarily for secure terminal emulation and file transfers between Unix-like systems. Xnest is used for running an X server within an X session, not for remote connections to Windows servers. Hence, rdesktop is specifically tailored for the purpose of connecting to Windows systems via RDP.
