For each computer that belongs to the Relay Server farm you are updating, copy the updated configuration file to the %SQLANY12%\RelayServer\IIS\BinXX\Server directory under the Relay Server web site home directory. The configuration file must be called rs.config if auto start is used.

From the %SQLANY12%\RelayServer\IIS\BinXX\Server directory, run the following command line to apply the configuration update:

rshost -u -f rs.config

Repeat the previous steps for each computer in the Relay Server farm that is being updated.
