Downloading files from MS Terminal Services server?

[Gilles]

Hello

	We have a Windows 2003 Server running the Terminal Services service
so that users can log on to that server and work there just like they
were on their desktop.

This server has some source code that I'd like to download and put
into Subversion on a FreeBSD server.

Problem is, the only way to connect to that server is through the
Terminal Services thingie, listening on the standard TCP3389. I don't
have access to the server, so can install eg. an FTP server.

I was wondering if there were a solution to automate the connection,
ie. connect/logon to that service, access the drive there to download
files, and connect out.

Thank you.
