A user's Windows PC is unable to connect to the network at a new branch...

ipconfig is a command-line tool that displays the current configuration of the network interfaces on a Windows PC. It can also be used to release and renew the IP address, flush the DNS cache, and display the routing table. If the PC is unable to ping the local gateway, the technician should use ipconfig to check the IP address, subnet mask, default gateway, and DNS servers of the PC. The technician can also use ipconfig /renew to request a new IP address from the DHCP server, or ipconfig /flushdns to clear the DNS cache.
