To start Replication Server automatically when you restart the system:
Go to C:\Documents and Settings\adminuser\Start Menu\Programs\Startup.
Add a new shortcut for x:\InstallDirectory\REP-15_5\install\RUN_servername.bat, where:
x is the drive name.
InstallDirectory is the name of the installation directory.
servername is the name of your Replication Server.
Replication Server now starts automatically after you restart the system.
