DHCP settings on Essentials 2012 R2 missing / DHCP server not running

Anyone have thoughts on this?

A recently configured Essentials 2012R2 box.  I set up dhcp on it and things were fine.

Last night there was a power outage.  THe server stayed up running on the UPS.

today, people can't get on the network / access the web.  the server is on the web.  I start DHCP from under admin tools.

There's no dhcp server set up.  I forget it I tried starting the DHCP service first or right click, choose add server and it comes up with the pool we had set, the leases page has listings for the computers, the scope settings are there, etc.  

And they are all set.

any thoughts on how the settings dissapeared / service stopped?

this is the only DHCP server (small network - 1 server and 10 PCs.

I've set up Essentials for a customer recently and, while I've not experienced a power outage, I've not had any problems with DHCP.

I can't imagine the scenario where DHCP just disappears without some external intervention and/or disk corruption.  What are the odds either of those occurred?

The common reason for why a DHCP service stops is because it detects another DHCP server on the network.

Verify that the router etc is not acting as a DHCP Server.  Presuming that the router wasn't reset or anything by the outage?
