Manually Generating the Certificate request for Lync Server 2010 and roles

All Lync Server 2010 servers and Lync 2010 clients use certificates and network communications in Lync Server 2010 are encrypted by default. Certificates are required for all internal servers that include Standard or Enterprise Edition server Front End Server, A/V Conferencing Server, Mediation Server, and Director. (I use the server name: Lync-FE)

I planned to deploy Lync Edge Server which controls how users outside the firewall can connect to your internal Lync Server. The Edge internal interface typically uses a private certificate issued by an internal certification authority (CA), but can also use a public certificate, provided that it is from a trusted public CA. (I use the server name: Lync-Edge)

The reverse proxy in your deployment uses a public certificate and encrypts the communication from the reverse proxy to clients and the reverse proxy to internal servers by using HTTP (that is, Transport Layer Security over HTTP) but for my testing I am going to use the my internal Enterprise CA to generate the certificate manually. (I use the server name: Lync-RP)
