Initially, all users are
sending a single stream

streams of up to 5 other
participants

17. LYNC ROOM SYSTEM (LRS)
@
@NICconf

18. • Familiar
• Native Lync
• Windows Embedded
7 Standard
@
@NICconf

19. •
Joining the LRS to a domain is optional
•
•
•
•
•
Requires manual import of certificates (for example, trusted root).
Easy certificate import.
Easy management by assigning Active Directory groups and
domain users administrative rights.
Joining to a domain has benefits
When joining LRS to a domain, pay attention to
•
•
•
GPOs (Group Policy objects) assigned to the OU (organizational unit) create a separate OU if possible.
Block Inheritance and No Override can cause unwanted effects - check!
Also settings for auto lockout, power management, additional
authentication, access to local drives, auto start of applications, and so on.
