Currently, we have two Windows 2008 R2 DHCP servers with split scope.
Due to budget, we need to move one of two Windows 2008 R2 DHCP servers to different site.
since the lease duration is 8 days, most leased IPs will be expired next week.
But, we have to shutdown one DHCP server today.
I think that I am going to delete exclusion and that's it.
Will those leased IPs (on DHCP server that will be taken off) that expire next week will
AS we know, when a scope is created, the default lease duration is set to eight days. Halfway through the lease period, the DHCP client requests a lease renewal. So, would you please tell us the exact time those IP addresses leased (on DHCP server that will
be taken off)?
In the event that the primary DHCP server becomes unavailable, the secondary DHCP server can continue distributing addresses. But if you delete exclusion,
the secondary DHCP won’t know which IP addresses the primary DHCP server had assigned, it will cause the IP address conflict eventually.
I would suggest you to delete exclusion after your IP addresses are released ( you can do it after eight days just in case) or you can enable address conflict
detection on DHCP server. Once you enable address conflict detection, it may increase the workload if your scope is large.
