Active Directory could not resolve the following DNS host name of the source domain controller to an IP address. This error prevents additions, deletions and changes in Active Directory from replicating between one or more domain controllers in the forest. Security groups, group policy, users and computers and their passwords will be inconsistent between domain controllers until this error is resolved, potentially affecting logon authentication and access to network resources.
Source domain controller:
%1
Failing DNS host name:
%2
NOTE: By default, only up to 10 DNS failures are shown for any given 12 hour period, even if more than 10 failures occur. To log all individual failure events, set the following diagnostics registry value to 1:
Registry Path:
HKLM\%5\%6
User Action:
1) If the source domain controller is no longer functioning or its operating system has been reinstalled with a different computer name or NTDSDSA object GUID, remove the source domain controller's metadata with ntdsutil.exe, using the steps outlined in MSKB article 216498.
2) Confirm that the source domain controller is running Active directory and is accessible on the network by typing "net view \\" or "ping ".
3) Verify that the source domain controller is using a valid DNS server for DNS services, and that the source domain controller's host record and CNAME record are correctly registered, using the DNS Enhanced version of DCDIAG.EXE available on http://www.microsoft.com/dns
dcdiag /test:dns
4) Verify that that this destination domain controller is using a valid DNS server for DNS services, by running the DNS Enhanced version of DCDIAG.EXE command on the console of the destination domain controller, as follows:
dcdiag /test:dns
