The choice of sender used for site to site communication depends on the existing network connectivity system between sites. If there are reliable, high-speed network connections between sites, plan to use the Standard Sender. If you have RAS connections between sites, select the appropriate type of RAS sender for your connection. If you want to send large amounts of package data for software distribution to sites using physical media instead of over the network, you can configure software distribution packages to use the Courier Sender.

When Configuration Manager 2007 sites are installed, the Standard Sender and Courier Sender are installed by default.

Choosing Configuration Manager Senders

Use the following table to choose the appropriate sender to use when configuring site to site communications.

Existing network connectivity between sites Sender


Use Standard Sender, the most commonly used sender, for sending to other sites on the same LAN, or on a WAN using routers, switches, or bridges.

Asynchronous line

Use Asynchronous RAS Sender for RAS communications over an asynchronous line.

ISDN line

Use ISDN RAS Sender for RAS communications over an ISDN line.

X.25 line

Use X25 RAS Sender for RAS communications over an X.25 line.


Use Systems Network Architecture (SNA) RAS Sender in RAS communications over an SNA link.


Use Courier Sender to send packages between the sites by using removable media instead of network wiring and protocols if you have a slow or unreliable link between a site and its parent. Courier Sender is used only for package distribution, not site-to-site communications.
