C:\rustserver>Start

It starts and stops here.

Create a batch file in the main server directory like this:

echo off
RustDedicated.exe +batchmode +server.port 28015 +server.hostname "[US] RustWorld S1 | Solo Duo Trio |" +server.maxplayers 300 +server.level "Procedural Map" +server.seed 352 +server.worldsize 3000 +chat.serverlog 1 +server.netlog 1 +server.saveinterval 300 +server.identity "NFO US S5" +rcon.port 28017 +rcon.password bobo +rcon.web 1 +query_port 28016

And make sure to change your rcon password if this works.
