DHCP Failover Oddities

[Olliesaurus]

Hello,

 

I migrated over my 2012R2 servers over to 2016 during the holidays and appear to be having an seriously weird issue.

 

PCs appear to be getting there APIPA address with a lease of 1 hour, when running ipconfig /release and /renew on the PCs, they get an address from DHCP however they keep the 1 hour lease and after that one hour revert back to APIPA.

 

If I disable and renable the adapter then it will give it the correct lease time of 3 days, however I am unsure whether this will follow across as it hasn't been 3 days yet.

 

Anyone else experienced this issue at all? Starting to wish I kept away from 2016 for another year or so!!

 

Thanks

This is really odd. I don't know how the underlying tech works with DHCP failover in MS server, but before it was a thing I always split the scope across two independent DHCP servers if I needed redundancy. Maybe give this a try providing that you would still have enough available addresses for the devices if the subnet was suddenly cut in half. Edited August 9, 2018 by Duke5A
