Windows Server 2012 Essentials Error: DHCP Failed To Install 0x800F0922

We are running a greenfield Windows Server 2012 Essentials with Exchange on-premises setup this weekend.

After setting the server’s IP to static we ran the DHCP Role install and hit:


Feature Installation

The request to add or remove features on the specified server failed.

Installation of one or more roles, role services, or features failed. Error: 0x800F0922

This particular setup is being done in our shop. So, we are using one of our own Cisco units to provide gateway services.

In the end it turned out that when we configured the Cisco ISA520 for the network’s subnet we had left DHCP on!

So, when that error happens make sure there are no DHCP services running on the network. Once we turned the Cisco DHCP service off we were able to install the DHCP Role, Authorize it, and set up our scope.

Thank you for posting your issue and your resolution. This is exactly what I had happen to me and your resolution fixed my issues as well. I turned off DHCP services on the Sonic Wall and DHCP installed fine.

Thanks again,

It's 2014 and Microsoft still can't provide a meaningful description to go along with an error number :-/

It helped me solve my problem (at home) , my server is running smoothly.

What is the purpose of a Radius Server, when AD is managing user logon privaleges?
