This can happen if you re-configured your DHCP Scope (or Server) and cleaned the DHCP lease database. Then the DHCP Client will try to re-use its previous IP Address, but it can conflict with another lease. You check this issue by changing the DHCP Scope to another IP range in the same subnet.
I am not sure if this is your issue as well, but just to make sure check it.

Do you need to release and renew every time your reboot?
Do you have any of the ip information hard coded like DNS?
Had DHCP been restarted or Server rebooted?
Are you using 1 or more dhcp servers with DHCP failover?

Yeah we've seen dozens of people wiht this, today. Every one of them got a Windows Update last night (you know, the new Windows 10 one's you cannot say no to?). All the guys who did not get an update yet are fine.

Hi Conrad,
As Darren mentioned, If client need to renew its address after it reboot, please catch packet to check if client has sent discover to request IP address.
Please ensure DHCP addresses pool is not expended.
When client lease expired, will it renew IP address for DHCP server?
Best Regards
John

This has not been the case, the only dhcp change i have made recently was to drop the lease time to 24Hrs.

# For Several PC's yes a reboot has been required each morning
Do you have any of the ip information hard coded like DNS?
# DNS is harcoded yes
Had DHCP been restarted or Server rebooted?
# DNS has been restarted, server has not been rebooted
Are you using 1 or more dhcp servers with DHCP failover?

The DHCP pool is not expended, the lease is 24 hrs and has been working successfully until now.
