Configure windows server 2003 to put temp RDP files on another drive

Hey everyone,

Here is what I'm trying to accomplish:

Move the temp files that are created by RDP to a separate hard drive.

Problem we are facing:

Each user has around 500MB of temp files depending on what they are doing on the remote desktop. That part won't change, so I need to find away to move the temp files off the C: drive and onto an external hard drive so we don't keep filling up the internal :)

I know, I also need to upgrade that computer and get it off of 2003, which is on the list but since it's a very stable system it's a little lower on the list...

I found these instructions for doing it on server 2008: http://technet.microsoft.com/en-us/library/cc755098.aspx but can't seem to find the same instructions for 2003... Any ideas?

Thanks in advance!
