My company is transitioning all user PC's to Windows 7 64-Bit in anticipation of the 2014 cutoff for Windows XP support. So far everything has been going great except for one specific piece of software that will not run in Windows 7. The current plan is to give everyone a cheap secondary PC to run this software but I feel that's a little much for software that's not even used all the time, although it is essential. I've suggested we install virtual machines but the company does not want to pay for the XP licences.

I have access to a copy of Windows Server 2003 that is no longer being used and I was wondering if it was possible to create a remote desktop server. I know it can be done on a one-to-one basis, but this is a 15 person helpdesk. I'd like to be able to support multiple remote dekstop sessions, each with their own logins and dekstops.

Is this possible? Are there any other alternatives to my issue?

FYI, I've been told that XP mode is only free for consumers. There are costs when used in a corporate environment.
