Reasons for DHCP error 0x79 to occur This error indicates that you have a predefined IP address on the computer and your device has assigned this IP address to some other device. The IP address is beyond the scope of the DHCP range.
The following error occurred: 0x79 means that your computer did not assigned an IP address yet from your network. Windows 10 has a capability to set up a new network connection that makes your device connected online again. There are two types of connection, static and dynamic.

How to fix DHCP error?
Register your DNS. Sometimes creating a dynamic registry manually for the DNS name and IP address will most likely fix the error.
Restart the DHCP server. The error can occur when a specific DHCP is stopped or your community is unable to connect to the service.
Reset TCP/IP.
Update and reinstall the driver schema.
Disable IPv6.
How to fix DHCP not enabled in Windows 10?
To re-enable DHCP or change your IP address selection, you can: In the Troubleshooting section, click Try to Repair as Administrator.
If everything went well, you should see a message saying “DHCP on network adapter is not enabled” has been fixed for the Ethernet or wireless adapter.
If the above probably didn’t work, press Win Contract + R (Win is the Windows logo key) on your computer keyboard and type ncpa.cpl.

The most common reasons for DHCP lookups are: Chrome OS is out of date error.
The firmware may be corrupted.

How does the DHCP client generate a DHCP request?
The DHCP client generates and broadcasts DHCP requests on the network. The DHCP relay agent intercepts these DHCP request broadcast packets and the adapter inserts the relay agent information (option 82) into the packet. The agent notification options information contains sub-options. The DHCP relay agent unicasts your DHCP packet to the DHCP server.
Which type of DHCP packets does a DHCP client send when it wants to leave a network?
To prevent the newly assigned home IP address from conflicting with the IP addresses of other clients on the network, the DHCP server itself sends an ICMP echo request packet before sending the DHCP offer. The DHCP server uses this packet to check if the given IP address compares to the IP addresses of other clients.
Why is my DHCP client not receiving packets from the DHCP server?
Due to the native VLAN configuration of all SW B trunk ports, this particular DHCP client does not receive any packets from the DHCP server. This is very easy to do, so you can troubleshoot when you “check” the DHCP client host. In such a case, assuming eth0 is the network interface used by the DHCP client host, it’s pretty simple:
How a DHCP server is prioritized by a client among multiple DHCP servers?
DHCP RFC, which states that if a large client receives multiple DHCP OFFERS (for example, from multiple servers), the client must decide which OFFER to activate. However, the choice of this method as an implementation detail for the DHCP client implementation remains.
What happens if a DHCP client Cannot communicate with a DHCP server?
If the absolute and client/server cannot communicate with each other, the consequences depend on whether the buyer cached the configuration from a previous major DHCP transaction. If it appears and the lease is valid, the client uses all cached data to customize its interface.
What happens when a DHCP client fails to obtain DHCP assigned address?
The DHCP server assumes that an address assigned by another DHCP forum on the same segment does not actually belong to its own pool. If the address doesn’t work, check the subnet mask/email IP address, the DHCP server checks if everything is from the global scope if it was set.
How does the DHCP client generate a DHCP request?
The DHCP client generates a DHCP request and sends it to the Internet. The DHCP relay agent intercepts the DHCP request packet and starts the relay agent information technology (option 82) in the packet. The Inform Agent option is a built-in sub-option. The DHCP agent relay unicasts the actual DHCP packet to the DHCP device.
Which type of DHCP packets does a DHCP client send when it wants to leave a network?
To prevent the newly assigned IP address from conflicting with the contact information of other clients’ IP addresses on the “network”, the DHCP server sends an ICMP request echo packet before sending a single DHCPOffer message. The DHCP server sends this packet to check if the IP address being dialed conflicts with the IP addresses of other clients.
Why is my DHCP client not receiving packets from the DHCP server?
Due to the native VLAN configuration of port SW B, the DHCP client does not receive any packets from the DHCP server. This is very easy to fix by “checking” the organization of the DHCP client. In such a case, if eth0 is the network interface used by the DHCP client host process, any type of simple:
How a DHCP server is prioritized by a client among multiple DHCP servers?
The DHCP RFC states that in case a client receives multiple DHCP OFFERS (eg from multiple servers), it can decide which OFFER will be accepted in which one. But this variant of the algorithm remains the implementation of the function of the developers of the DHCP client.
What happens if a DHCP client Cannot communicate with a DHCP server?
If the client and server cannot communicate with each other, the consequences depend on whether the client cached an assembly from a previous DHCP purchase. If this is the case and the one-time lease is still valid, the clients use the cached data to configure the interface.
What happens when a DHCP client fails to obtain DHCP assigned address?
The DHCP server assumes that the address was assigned by another DHCP server in the same hop, unless it is from another of its pools. If the subnet mask/IP address check fails, the DHCP server will check if the idea comes from the parent set if only one is defined.
