I'm about to get a new server to replace current SBS2003. Since we are seriously looking at Exchange Online from Microsoft, the SBS 2011 would only do file sharing, DHCP, DNS, WINS and print server. We have another Server2003 for Terminal Services now and would really like to keep it as we have 32-bit applications that are important to our business (not sure if those will run on newer 64-bit OS).
1. SBS2011-E seems adequate to do the server functions stated above or would I still need the Standard version because of terminal services or RDS?
2. Can I still use the old 2003 terminal server with SBS2011-E? If so, do I still need new CALS?
