Thanks for the answers. I have just spend the last few days trawling through a ton of tutorials to get a better understanding of the basics :-)

However I can't seem to find a good guide on how to use an XML file for storage (Step by step). I read on another forum, that it wasn't recommended to use a XML file if you had more than 20 users in the DB? Should I reconsider, and go with a SQL or Access DB instead?

Re: the RDP connection. This was fairly simple, as I just launches mstsc with the /v: Server IP:Port parameter.

Thanks again.
