ADWS Critical Error

DNS

The DNS server is waiting for Active Directory Domain Services (AD DS) to
signal that the initial synchronization of the directory has been completed. The
DNS server service cannot start until the initial synchronization is complete
because critical DNS data might not yet be replicated onto this domain
controller. If events in the AD DS event log indicate that there is a problem
with DNS name resolution, consider adding the IP address of another DNS server
for this domain to the DNS server list in the Internet Protocol properties of
this computer. This event will be logged every two minutes until AD DS has
signaled that the initial synchronization has successfully completed.
