你好:
1. YES
2. Windows Server Foundation can be used as an Active Directory server or domain controller, and can also join a domain as a
member server or domain controller (but the 15 user limit still applies across Active Directory scenarios)

Foundation is targeted at small server environments. Foundation is pre-installed on servers with up to 8 GB of RAM and a single processor. Up to 15 user accounts are included with the OS, including use of Active Directory. Windows Server Client Access Licenses
(CALs) are not required for use of the Foundation server, but terminal server CALs and Rights Management CALs may be required. Roles include DHCP, DNS, file server, and print server. Foundation is capable of running line of business server applications for
small businesses. Foundation is supposed to make initial purchasing simple for small networks to provide a single server solution for all IT needs. Foundation is a lesser-powered server than the popular
Windows Small Business Server (SBS), which has additional options including Exchange, SharePoint, and SQL Server.
