DCHP splitscope

Hello experts,

I have two DC's with the DHCP role installed. To have some redundancy I've created a 80/20% splitscope according to Microsoft's recommendation.

The weird thing is that (eventhough I've set the delay on dhcp1 to 0 and dhcp2 to 1000ms) dhcp2 leases addresses while dhcp1 is up and running with 46% available addresses.

I've expected that only dhcp1 would lease addresses, unless dhcp1 is down.

Please advice.

Kind regards,

Len

My settings were correct, now I've rebuild my split-scope and it works. Probably a bug when I build it the first time

Hi Len,

Sounds like you have done all the right steps, could you post an image from the fully expanded DHCP MMC ?  (i want to see the (split-scope) extension on both machines)

My first impression would be there has been a fault while setting the DHCP delay on dhcp2.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Hi

Could you investigate why there is an exclamation point in the second DHCP scope?

Yep, because there is only 1 ipaddress left to give out. And that's why I noticed that my splitscope isn't running well.

Hi again,

I will be on my holidays in two days so i am sorry if i am unable to help you throught the end.
Could you summarize the settings used during deployment? I have a feeling there went something wrong by splitting the scope (or check your DHCP logs if server1 reported to be down)

For a good step by step i could recommend reading this link.

Please dont delete this thread, it could be helpfull for others to see a split scope can be setup correct YET not functioning.
Better mark your last answer as the solution providing yourself 0 points (that reminds me of the Eurovision songfestival and dutch scores but hey! offtopic :)
