Windows XP equivalent of "tail -f"?

Using Windows Powershell, you can use Get-Content < filename > -wait

There's also a discussion of a Windows Server 2003 tools package that has a tail program which supports -f

I have had good luck with http://sourceforge.net/projects/tailforwin32/. It has some nice options for fonts, colors and keyword highlighting. Feels lightweight and fast to me.

Just use the tail program from the cygwin project. this is "just" a ported UN*X tail command.
