Both the retail and checked (debug) versions of Windows 2000 include a debugging client that allows the kernel to communicate over a serial line with the WinDbg debugger. The debug client must be enabled on the target system during the boot process.
To enable the debug client, select the OS for the target machine with cursor keys while the system boot screen is displayed. Press F8 and select (with cursor keys) the option for Debugging Mode. Press Enter twice to boot the system.
