Knowing how to clear the ARP cache on a workstation or server can often be a good step in troubleshooting connectivity problems.

The Address Resolution Protocol (ARP) is very crucial for TCP/IP network communication. If you begin to notice network connectivity problems such as particular web pages not loading or not being able to ping certain IP addresses then clearing your ARP cache is a good place to start.

You can view your workstations ARP table by typing “arp –a” from a command prompt. Deleting the ARP cache is just as simple and can be done from a command prompt by typing “netsh interface ip delete arpcache”.
