I was currently having problems with people not being able to receive emails. on investigating, the exchange server is all up and running as it should be but when looking in the event viewer i noticed a load of NETLOGON errors Event ID 5774. When checking this error code it seems to point to dns problems. I checked dns and didn't see any error so i thought it might of got itself into a twist so i uninstalled dns and reinstalled it. What i have now noticed it the _msdcs.domain.com is missing from the forward lookup zones. I think this might be one of the causes, how do i get this zone to reappear. I have rebooted several times with no luck. This is a W2K3 single domain controller.
This is the error i get in the event viewer:
The dynamic registration of the DNS record '_ldap._tcp.Default-First-Site-Name._sites.DomainDnsZones.domainname.co.uk. 600 IN SRV 0 100 389 BGF-SERVER.domainname.co.uk.' failed on the following DNS server:
DNS server IP address: 220.127.116.11
Returned Response Code (RCODE): 5
Returned Status Code: 9017
For computers and users to locate this domain controller, this record must be registered in DNS.
Determine what might have caused this failure, resolve the problem, and initiate registration of the DNS records by the domain controller. To determine what might have caused this failure, run DCDiag.exe. You can find this program on the Windows Server 2003 installation CD in Support\Tools\support.cab. To learn more about DCDiag.exe, see Help and Support Center. To initiate registration of the DNS records by this domain controller, run 'nltest.exe /dsregdns' from the command prompt on the domain controller or restart Net Logon service. Nltest.exe is available in the Microsoft Windows Server Resource Kit CD.
Or, you can manually add this record to DNS, but it is not recommended.
Error Value: DNS bad key.
