Srini is correct. You cannot use SBS2003 as an application terminal server. However, you could use Win2k3 or 2k in a virtual machine. The better alternative for application terminal server would be to add Win2k or Win2003. The advantage with 2000 is XP Pro all come with TS license for 2000 but need separate licenses for Win2k3.
Two users can connect to the server in administrative mode at one time.
Now terminal services is completely different from RWW. The limit on RWW should be 75, the number of CALs one can purchase for SBS2003. The only limit one should have for remoting into your "network" not the server would be the number of CALS coupled with the number of computers. So 10 PCs with 10 CALs, you should be able to have 10 concurrent users into each person's respective computer. Or they could log into any PC, but if many were going to log in at one time, it would be best to stick to their own PC.
