In this tutorial, we learn how to clear the ARP cache. First, go the command prompt on your computer and type in "C:/>netsh interface ip delete arpcache Ok". Press 'enter' on your keyboard and then it should be cleared out. If you want to view your ARP cache, type in the command "C:/>arp -a". If this fails, then you will need to use Microsoft Windows to repair the network connection. If this doesn't work, talk to the person that manages your connection. If successful, this will help make your computer run faster and programs be more efficient, enjoy!
