MessageStats 7.6 - Report Pack for Lync & Skype for Business User Guide

About This Guide Installing the Report Pack Configuring MessageStats for Lync Managing your Database Using the Lync and Skype for Business Reports Appendix A: Configuring RPC through a Firewall

Configuring RPC on the Lync or Skype for Business Edge Server

In a default Windows installation, the RPC program is configured to randomly assign server ports to any port above 1024. It is unwise to open every port over 1024.

The recommended procedure is to configure RPC to use a specific range of ports. Microsoft recommends using ports 5000 and up. Port numbers below 5000 may already be in use by other applications and could cause conflicts with your DCOM applications.

Microsoft also recommends that a minimum of 100 ports be opened. This example shows how to configure RPC on the Edge server to use ports 5000 to 5100.

Configuring the ISA Server

Once you have configured RPC to use a specific set of ports on the Edge server, you make those ports available to the MessageStats server by opening the required ports on the firewall.

In addition to opening the dynamically-assigned ports, you also must open port 135. Port 135 provides access to the RPC Endpoint Mapper. The port must be available for proper operation of RPC.
