dhpcd hogging all recources

I manage a Linux server for my friend which runs a Minecraft server, I consider myself a total noob in Linux but i know how to work with it a little. Since the server is at my friend's house I use powershell to ssh into the server and start the startup script inside a screen. But after a while a process starts running /bin/dhcpcd and it always uses at least 50% of the CPU power. It also starts when I don't start the minecraft server but it never runs at startup. What is this, can I disable it and if so how?
