Which version for Terminal Services

I have a small network currently have Windows 2003 SBS. Setup as a domain with a single DC. We currently use Terminal Services in our remote office but are limited to 2 sessions as I have it in Administrative mode. I also understand that the SBS edition does not support application mode.
So I am planning on replacing the server. I want to make sure I don't make a mistake with the version of 2003 server.
Does the standard version have full support for application mode? or do I have to go with Enterprise edition?
Any help on this is greatly appreciated!

 

I think standard version will be fine. Have a look at this:

I can't see any mention to being restricted to a certain version of 2003 server, so I expect that it will work on standard as well as enterprise.

If all you want to do is add terminal services to your network and you have no other issues with your current server, I'd recommend that you don't replace the SBS server. Instead, add a second server and dedicate that to terminal services. Oh! and get one with lots of RAM!
