I have a SBS 2011 Server (running on a Dell PowerEgde T310). This morning we had critical ISP issue resulting in some downtime. After the Internet Connection has restored I cannot via the DHCP or DHCP leases via the DHCP MMC or adding the DHCP service to an MMC console. On opening the DHCP window I can see the Server Name. When I click on the Server I receive a Cannot find the DHCP Server error message.
This is not a migration, Server has been online for over a Year.
So far I have:
Disable the NIC and re-enabled. (Single NIC).
Rebooted the Server.
Ran the Connect to the Internet Wizard (Wizard found the Router and Server IPs)
Manaully restarted the DHCP service (Service is Running).
Reviewed the Event Logs (no indications in the Event Logs).
Unathorise the DHCP Server and re-added the Server.
LAN users are still receiving IP Addresses.
Just wondering if anyone has come across this before and if they have a fix.
