Domain Controller and exchange server failing after power failure

By neani001 ·
I have an environment where i am running AD and exhchange on one server.I had a huge power failure and now my exchange server is not delivering email to mailboxes. I am able to send out emails on that exchange server but i cannot received anything.I am getting event id 2102(Domain Cotrollers not responding when i start the server). This server is also a DNS on the network.When i ran a DCdiag yesterday i got this error { The host could not be resolved to an
IP address. Check the DNS server, DHCP, server name, etc
Although the Guid DNS name
( couldn't
be resolved, the server name ( resolved to
the IP address ( and was pingable. Check that the IP
address is registered correctly with the DNS server.}
Does anyone know howi can resolve this please.This problem happened on sunday.I would appreciate it if some helped me.
