We're a small business that had two DCs that also provide DHCP and DNS, one was also a file server. I built a new file server and transferred the files over the weekend. Today, there are problems with network connectivity. Machines with static IPs and those with existing DHCP leases are fine. The problem is, no one can obtain a new lease. I tested this on a few machines on a few machines by trying to manually renew their lease, which left them with no connectivity
Anyway, when I checked the event logs, it said that the DHCP server (on both machines) couldn't find a DC to authorize to. I'm not sure how that would exactly work since they both run on DCs. Anyway, I manually restarted the DHCP service, and checked the logs again. Both said that they were up and running and now servicing clients. When I look at DHCP under administrative tools. It initially says "Not connected", but when I click on it, it says "Running."
I'm a bit frazzled from the whole weekend and this morning, so I'm probably just missing something obvious. Any help would be appreciated.
TIA.

Both servers are authorized and have the green up arrow.
The DHCP server service is listed as "started" under services.
Client machines have normal network connectivity if I assign them static IPs. I might just go do that on the few machines have expired leases for the time being...
