(A Standard Edition server is regarded as a logical pool whose front and back ends are collocated on a single computer.) Trusted Servers In Lync Server 2010, trusted servers are the ones specified when you run Topology Builder and publish your topology. The published topology, including all the server information, is stored in the 11

Microsoft Lync Server 2010 Security Guide Central Management store. Only servers defined in the Central Management store are trusted. In Lync Server 2010, a trusted server is one that meets the following criteria: The FQDN of the server occurs in the topology stored in Central Management store. The server presents a valid certificate from a trusted CA. For details, see Certificates for Lync Server 2010 . If either of these criteria is missing, the server is not trusted and connection with it is refused. This double requirement prevents a possible, if unlikely, attack in which a rogue server attempts to take over a valid server’s FQDN. Additionally, to enable Microsoft Office Communications Server 2007 R2 and Microsoft Office Communications Server 2007 deployments to communicate with Lync Server 2010 servers, Lync Server 2010 creates containers during forest preparation for holding lists of trusted servers for previous releases. The following table describes the containers created to enable compatibility with previous deployments.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
