Terrariaserver.exe is the easier one of the two, you just need to edit the server config file and specify the amount of slots. The file can be found at either C:\Program Files (x86)\Steam\steamapps\common\terraria\serverconfig.ini or if you don't have the x86 folder, at C:\Program Files\Steam\steamapps\common\terraria\serverconfig.ini. You need to find the line that says #maxplayers=8 and remove the hash at the start. After you've done that, change the number to your preferred number, and restart the server.
