I have a Small Business Server 2003 with my Pastel Partner 2009 installed on. It is also my DC,DNS,RAS and DHCP server. User A(AD Account1) will logon from the outside via VPN into the SBS 2003 server. And from there the User A(AD Account2) will use a different account to RDP into a 2nd Server which is my terminal server running Windows Server 2008. How many of what cals will i need in total for the user. The reason the User A has two AD accounts is because of Group Policy being very strict under the RDP user for obvious reasons. I know i need 1 terminal server cal, 1 Windows Server 2008 cal, but how many SBS cals, because of the one user having two different user accounts and using them simultaneously.
