My Google-fu is failing me today. I would like to blame the bad office coffee, the fact that it is a Monday, and the lack of information online...but maybe it is my fault. Either way, I hope that you can help:

Can the IPAM role on Windows Server 2012 R2 discover and manage WS2008R2 DHCP clusters, or can it only manage standalone DHCP servers?

If it can manage DHCP clusters, should I have the IPAM service discover the cluster service name, or the individual DHCP cluster nodes?

  • Update: After fixing firewall rules on the DHCP cluster nodes, I again tried to discover the DHCP cluster with MS IPAM. This time it responded with an "unsupported operating system" message. Thus, it appears that a clustered DHCP service cannot be managed by IPAM. Of course, once a Windows service (e.g. Print or DHCP) is clustered, we must not manage it by connecting directly to a node, so it appears that clustered DHCP is not compatible with Microsoft Windows Server 2012 R2 IPAM. However, I have yet to find any documentation that confirms or contradicts this finding. – SamErde May 12 '14 at 14:59

Apparently IPAM is looking at the operatingSystem attribute on the server's computer account in Active Directory in order to find out whether it is running a supported OS.

In order for Windows Server 2012 IPAM to discover and manage a Windows Server DHCP cluster, you have to open the properties for the AD computer account of the cluster service name, go to the Attribute Editor tab, and edit the operatingSystem, operatingSystemVersion, and operatingSystemServicePack attributes to reflect what the DHCP cluster node servers are running.
