So the DHCPNAK are not unexpected but the x.x.4.251 server could be defined as a rogue DHCP server. It is then expected for that server to send NAK to clients who request addresses that the server cannot handle. It's likely the configuration of the server, including pools of addresses, was not adequate to answer DHCP Request. I'll make this the answer to this post based on your last comments so it can help others as well.įirst x.x.4.251 was probably not expecting DHCP traffic from your clients. Where should I look in the capture, or on the network do determine possible solutions? The conversation completes but then repeats, over and over. Most spoke to one end of the conversation not receiving or acknowledging part of the conversation, but that's not the case for us. I did several Google searches and couldn't really find anything that described this behavior. Two helper addresses are part of the vlan config. The two DHCP servers are on the server vlan, and the users are on the user vlan. One went for at least 20 minutes this morning when that person added a new computer to the domain.

Total speculation on my part.īut I also noticed that some users have a series of repeated DHCP conversations for minutes. Perhaps this was because my IP address (which is reserved) hadn't cleared in some table? We have two DHCP servers. But the second four part conversation had the correct lease time as set on our MS DHCP servers. I also did notice that the original four part conversation had a lease time of one minute. But the original few four part DHCP conversation was in perfect order. In two of the eleven, I did notice the ACK to the previous request came in after the next discovery. This morning I did an ipconfig release then renew on my computer to start off the DHCP conversation and it repeated 11 times. Using Wireshark I can see that the typical DHCP process (discovery, request, offer, ack) repeats many times for users, typically a dozen times. And event logs for the affected AS400 users show that outlook loses connection to the exchange server for a few seconds.
We have received reports that streaming video for some users stutters along. They are on different switches, but same VLAN.Įveryone else on that VLAN seems to be working okay, but their apps are not as sensitive. This is a very small group of users, maybe a dozen out of 200 hundred plus. Your feedback goes directly to our products teams and helps us shape the future of Office for users around the world.Recently some of our users have complained that their sessions to our IBM AS400 drop their connection during the first hour or two of the work day, 8am-10am. Let us know what's working well, if there are problems with our products, or if you have ideas about new functionality that would improve your experience.
