DHCP offering invalid addresses

Hello. I am doing live streaming of our Stake Conference. On one session I note the laptop we are using would not connect to the internet. We are hardwired to an Ethernet port in the chapel. I noted that DHCP gave me a TCPIP of 192.168.0.X. This address does NOT work on our network. Rebooted computers, switches, firewalls, routers to no avail. Same type of address being presented. Finally after 4-5 reboots of the firewall (assumed the DHCP is residing there) it began working again. Finally getting addresses in the 192.168.108.X range, which is correct.

Anyone have any idea what is going on? Any workarounds that kick the DHCP into correct service? Thanks.

I'm betting that someone brought in a home router to use as a switch (most likely in the clerks office) and failed to turn off the DHCP services in that router. Your laptops were getting addresses from the rogue DHCP.

Of course....that makes perfect sense. I heard a rumor that a clerk did in fact put a router/switch on the network for their uses. Now the hard part...finding it.
