Introduction to Debug View from Microsoft:
DebugView is an application that lets you monitor debug output on your local system, or any computer on the network that you can reach via TCP/IP. It is capable of displaying both kernel-mode and Win32 debug output, so you don't need a debugger to catch the debug output your applications or device drivers generate, nor do you need to modify your applications or drivers to use non-standard debug output APIs.
DebugView works on Windows 95, 98, Me, 2000, XP, Windows Server 2003, Windows for x64 processors and Windows Vista.
