Has anyone tried using this yet? I am relatively disappointed in it so far...I CAN"T GET THE %*$(% thing to work

I am running Windows Server 2003 SP2. The WDS Legacy app runs fine (this is more like RIS). However, when I use the new WDS snap-in, it gives me an error message when I am on the "Remote Installation Folder Location" screen. The error message is a 'Configuration Server Error' and says "The filename, directory name, or volume label syntax is incorrect"
I've tried uninstalling/reinstalling WDS as well as searched the Internet and Microsoft for a solution...I got nothin'.
Anyone on here have a good ideas? I know this is realtively new, but no real luck. Some of the command line switches using the WDSUTIL tool echo back errors too.
Thanks,
Jimmy
