Hi Bert and James,

Thanks for the detailed reply. A couple of follow up questions:
- MS RDP/RDS licensing allows per user license so if I can have one rdp user created and have the entire office connect to AC TS using that user, it would save us on TS CAL's
- What I meant with multiple instances was running multiple customers (each having a different database) on same Windows 2008R2 server.

We do hosting for a different EMR which runs on sybase and it allows us to do both of above. Basically we have multiple customers, each with their own database running on one windows 2008r2 machine (sybase shows each client running as a service and we can turn on/off/restart each of them individually). There is another machine which is "Apps server" running terminal services and that is where the clients connect to. All employees of each customer (Dr ABC MD LLC., Healthy Hearts LLC etc) will have one unique RDP username/password (which really they are not aware of since it is stored in the 2X application server file). This way we only use 1 TSCAL for each customer.
