Overnight, the DHCP server went down. The server provides dynamic IP address for the computers in the office network (using the IPv4 standard). You have the server backup but not all of the computers can connect to the network. What command/commands do you use to reconnect the computers to the server and obtain an IP address?
  1. Ipconfig /refresh
  2. Ipconfig /release and then ipconfig /renew
  3. Ipconfig /release and then ipconfig /refresh
  4. Ipconfig /all
Explanation
Answer: B - Ipconfig /release and then ipconfig /renew will allow the computer to reconnect with a new IP address.

Key Takeaway: Using ipconfig /release will prompt the NIC to release the previously assigned IP address and the ipconfig /renew will send a request to the DHCP server for a new IP address.
