Event 1041, DHCP-Server

Question

_{Sunday, April 3, 2011 8:14 PM}

Hi!

I recieve DHCP event ID 1041 error in the event log. The message says "THe DHCP service is not servicing any DHCPv4 clients because none of the active network interfaces have statically configured IPv4 addresses, or there are no active interfaces."

I can see why I get this error, because the info in the short desciption is true. I have no statically configured IPv4 addresses. It is a IPv6 only network, and the DHCP server is not supposed to service IPv4 at all.

Everything is run in an isolated Virtual LAN on Hyper-v with VMs only. All servers (including host) is running Windows Server 2008 R2.

I know I can disregard of this message as it will not affect anything in my network, but I just can't live with a DHCP event log with a red cross every hour. ;) What am I missing? Do I have to add a static IPv4 address even though I don't want to (and feel like I shouldnt have to)?

Cheers

Hi Leyan,

Thanks for posting here.

> Why is it that I can run DHCPv4 with a non-static IPv6 address without errors in the event log, and not the other way around then?

This is due to the features of IPv6,please take time to read the articles below for getting a better understanding:

Internet Protocol Version 6 (IPv6) and Internet Communication

http://technet.microsoft.com/en-us/library/cc783437(WS.10).aspx

The DHCPv6 Protocol

http://technet.microsoft.com/en-us/magazine/2007.03.cableguy.aspx

Please understand that Windows server 2008 provides DHCP services for both IPv4 and IPv6 at same time, this mean that even if you configure just provide DHCP for IPv6 , IPv4 DHCP service will also be started , however setting static IPv4 address is a requirement for IPv4 DHCP service ,in this case we still need doing this otherwise this warring will continually prompt. And we’d also not recommend to disable IPv4 if you want to deploy this host in a native IPv6 environment.

If you have any IPv6 question please also post to our IPv6 forum:

You must assign static ip address for dhcp server.

Please refer to this article.

Thanks

Ok, well then it is inconsistent. Why is it that I can run DHCPv4 with a non-static IPv6 address without errors in the event log, and not the other way around then?

I have no problems giving it an static IP address on the IPv6 side, and I allready have. I still feel that if I'm to service IPv6 only I should be able to uncheck the IPv4 protocol of the NIC, without getting errors in the event log.
