How can I mount an FTP to a drive letter in windows?

I'd like to mount an FTP to a drive letter in windows, I've used Novell's NetDrive, but there are two main problems, 1) it tends to slow down computer alot 2) it doesn't seem to work at all under Vista.

Are there any applications that will allow me to mount a remote FTP to a local Drive letter, or is there a method built into Vista for it?

Answer

I have used WebDrive for several years without any trouble.
