Remote Procedure Call (RPC) Service Endpoint Functionality

Updated: February 22, 2008

Applies To: Windows Server 2008

Administrators can configure the Remote Procedure Call (RPC) service (RpcSs) to listen on a subset of the computer's network interfaces using RPC Firewall Filters. The administrator can use RPC Firewall Filters to block some interfaces from being accessed over a given network interface and while allowing other interfaces to be accessed over the same network interface. RPC Firewall Filters make it possible for an administrator to configure network interface access on a per-interface level of detail.

RPC Firewall Filters comprise a set of rules and conditions that the administrator specifies. The Ep_add Layer filter supports port addition to processes that host a given interface. By creating an Ep_add Layer filter, an administrator can force an interface to receive calls over the port that the administrator specifies when the administrator creates the filter. If the port that is specified in the RPC Firewall Filter is already in use, the system registers a port conflict error.
