How to configure a trusted application server? 

I have been publishing issues and their resolution since long, today I want to take break from issue / resolution and want share some information. I don’t waste your valuable time to reading full documents and then find small information.

So here is the today’s informative question. ‘How to configure a trusted application server?’ obviously on Lync. 

Basically trusted application is an application based on Microsoft Unified Communications Managed API (UCMA) 3.0 Core SDK that is trusted by Lync Server 2010.

You can follow below steps and configure the trusted application server.

1.  Log on to the computer where Topology Builder is installed as a member of the Domain Admins group and the RTCUniversalServerAdmins group. 2.  Start Topology Builder: Click Start, click All Programs, click Microsoft Lync Server 2010, and then click Lync Server Topology Builder. 3.  Select Download topology from existing deployment, and then click OK. 4.  In the Save Topology As dialog box, click the Topology Builder file you want to use, and then click Save. 5.  In the right pane, right-click Trusted application servers, and then click New Trusted Application Pool.   6.  Enter the Pool FQDN of the trusted application pool, select whether it will be a single-server or multiple-server, and then click Next. 7.  On the Select the next hop page, from the list, select the Lync Server 2010 Front End pool.       8.  Click Finish. 9.  Select the top node Lync Server 2010, and then, from the Actions pane, click Publish.
