Event Log Event 1001: DHCP Client

Hi there.

I've spent a good 10 hrs searching for a fix to my problem - including SevenForums - with no success...

I just purchased a Clevo P170HM with i7-2920XM processor and GTX 485 graphics card. It's an awesome system. I went into event log, and after noticing a few critical and error events I decided to fix the important ones...

I've done this - except for the Error - Event 1001 DHCP Client:

"
Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0x0016EB059618. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server."

This is the most common of the 1001 events, but others have network address' of 0x001F81000100 and 0x00158315A1C0, all with the same error 0x79.

Many people have thoughts on what's causing it, so here's what I've done:

- Confirmed all my network drivers etc are all up to date
- Followed and completed the full Windows help file on the topic
- This includes pinging myself and the DNS address' to confirm responses
- Completed a release and renewal of the ipconfig command on the DHCP lease.
- Disabled ipv6 in all network adaptors
- Disabled ICS in all network display adaptors (after restart, checking services)
- Disabled/enabled Bonjour to eliminate
- Checked services of DNS auto, DHC auto etc etc
- Turned off Virgin Broadband on one restart to see if the error occured (which it still did, so I'm sure it's not that connection)
- A few other things I can't remember over 10 hrs...

I thought it might be my Bluetooth network coming up in Network and Sharing Centre as 'Unidentified Network', or that it is a work network where my Virgin Broadband USB is on a home network in Network and Sharing Centre. I cannot amend the Bluetooth 'Unidentified Network' name. I also noted that my Bluetooth connection is coming up as an 'Internet connection' rather than a PAN, but this could be because my iPhone has been discovered, added and used as a tethering on the internet on occasion. My bluetooth is a separate USB and not on my wifi card.

When I completed ipconfig /all to check on this, I noted that all have DHCP enabled except for Virtual Netork #1 and Virgin Broadband.

I also noted that my Intel 6300 N Ultimate wifi card did not have the ipv4 address listed and did not have (preferred) next to it. When I conducted the ipconfig /renew command, my 6300 N wifi card could not be included in this because it has not been connected to a network - I use my Virgin Broadband USB for internet (at least until I trade this in for a prepaid wifi device). Maybe completing the ipconfig /renew command when I have a network connected to the 6300 N wifi card?

There are STACKS of users out there trying to fix this issue. I believe most are not finding their answers and have probably tried everything I've listed as doing without success.

I'm hoping by displaying my efforts on this that we will get an answer hopefully that others can use to get rid of this error that pops up on every system boot...

many MANY thanks in advance for your help. It is GREATLY appreciated...

I've had a problem with DHCP renew not working properly for months, not sure when it started. I've tried registry settings, new drivers, etc. Nothing has worked. Often I only lose my IP address for a second or less, but of course, this is enough for any open connection to drop.

After DHCP renew fails to the point of my connection being lost, some other DHCP mechanism kicks in which (almost) always works at once.

Right now, however, the problem seems to have gone away.

What I did was uninstall the driver from my network card (Realtek RTL8168D/8111D), again and again, until it was no longer possible to uninstall the remaining driver (Windows default I'm guessing).

Then, after some time, an optional update appeared in Windows Update. It was a network driver that was released by Microsoft on May 14, 2009.

After I installed this driver, DHCP renew has never failed.

I'm sorry if this gives you false hope in solving your issue (which perhaps is different), I just had to provide the one thing that actually worked for me. I know your frustration!
