BAD_ADDRESS

Hi,
On our network we started getting duplicate IP addresses handed out, we can no longer receive a DHCP IP address from our DHCP server.
We created a second scope to match the first one on a different server, deactivated the first one and activated the second one, same results.

We are constantly getting "BAD_ADDRESS" on the DHCP server, never seen this before...

Any ideas as to why this is happening?

Please respond back as soon as you are able as we are currently having major issues on the network.

Thanks...

Hi,

1. As work around, firstly delete all client except reserved IPs from DHCP.
2.  turn on the conflict detection in properties of DHCP server.

I have seen this when there is a rogue DHCP on the network.  A user plugs in a wireless access point that is configured with DHCP enabled and it spits out addresses to machines in the same subnet, then your REAL DHCP server also responds to some requests giving out what it thinks are good addresses and it finds that those addresses are bad.  

Have you looked for a rogue DHCP server on this network?  How long has it been occurring?

Santosh: I would leave the conflict detection configured.  It's a good thing.  Why workaround the solution when we can find the solution and fix the problem?  

ElliTech: You can use Wireshark to determine if there is a rogue DHCP.  I would check that first since every instance I have run into of this actually on sites this is the problem.  If you haven't used Wireshark to do this, it can be daunting but I ran across a good video awhile back that may help you in troubleshooting this specifically using Wireshark: https://www.youtube.com/watch?v=uyvEa7Nh80A

Years ago I have faced above issue caused by Symantec End Point protection (network access protection component) on DHCP server

Please disable antivirus software completely, then delete all DHCP BAD_Address lease from console, restart DHCP service and check if it works

If this resolve your issue, you can check with AV vendor to resolve this issue permanently

@  Joe Jenkins,

see the author question.

"we can no longer receive a DHCP IP address from our DHCP server."

So, my thinking is workaround should be provided first, instead of solution, as such type of issue can take longer time.

detecting rogue dhcp server:
http://blogs.technet.com/b/teamdhcp/archive/2009/07/03/rogue-dhcp-server-detection.aspx   (there is a tool to download at the end of the article)

Delete all the client leases on the DHCP server.
Monitor leases
When you get a BAS ADDRESS again, try to understand what machine caused it (sometimes it is a defective NIC that causes such issue).


Use Wireshark or MS Network Monitor to examine DHCP packets (filter on UDP 67 and UDP 68) and to understand what happens
