EventID 1001 DHCP Your computer was not assigned an address from the network


log onto wondows got the following error under event viewer:

" Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0x685D4361718D. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server."


Method 1
I would suggest that you disable the Internet Protocol Version 6(IPv6) on the network adapter and check if it helps. 
a.     Right click on the Network icon in the System Tray and click on Network and Sharing center.
b.     Click on Change Adapter settings.
c.     Right click on Network Adapter and Choose ‘Properties’.
d.     Uncheck “Internet Protocol Version 6”.
e.     Click on OK.
Note: By disabling IPv6, you will not be able to use Windows Meeting Space or any application that relies on the Windows Peer-to-Peer Networking platform


Method 2
disabling my Wireless Connection #2 (Microsoft Virtual WiFi Miniport Adaptor) network adapter.  I found this by comparing the MAC address listed in the error message with the output of CMD>ipconfig /all.  Noticed that this adapter continuously tried to communicate with my DHCP server, and I wasn't even using it



Method 3

1- unplug you LAN cable and wireless connection Go to  "Ethernet Adapter local area connection 2" properties
2- select "Internet Protocol Version 4 (TCP/IPv4)"
3- press Properties button
4- select "Use the following IP address:" option and set this ips
IP=192.168.1.105
subnet mask=255.255.255.0
default gateway = your router ip address such as 192.168.1.1
5- from second section select "Use the following DNS server addresses:"
set "PreferAlternate DNS server:" your router default ipfor example 192.168.1.1
6-press ok and try to connect through lan then wireless

Method 4:
Network and Sharing, manage network connections, and disable the bluetooth networkin

Method 5:
 check the DHCP "lease" time of the router and make sure it's set as high as it can go. Occasionally people will set it to 60 minutes, but that will cause the router to try to reissue the IP address hourly and that could potentially cause what you're experiencing.


Method 6:
services.mscLocate the DHCP Client service.
Make sure it's Started and the Startup Type is set to Automatic.
If the service is already Started, try Stopping and Restarting it.


Method 7:
Click Start > Programs > Accessories > right-click on Command Prompt, select "Run as Administrator" to open a command prompt.

In the Command Prompt, type in the bold text, one command after the other, pressing Enter between each of them:

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults: netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults: netsh int ipv6 reset reset.log

Reboot the computer.

PS: Try using Google Public DNS  OpenDNS.

Method 8:
disable the Computer Browser service in Windows services, that will stop it from trying to connect. Truthfully, if you have no other networked computers, just to go the Network properties and disable file/print sharing, that will stop several services, including the computer browser.
