Windows DNS Server Interview Questions –Part6



Windows DNS Server Interview Questions –Part6 and Final
51. Should I point the other Windows 2000-based and Windows Server 2003-based computers on my LAN to my ISP's DNS servers?
No. If a Windows 2000-based or Windows Server 2003-based server or workstation does not find the domain controller in DNS, you may experience issues joining the domain or logging on to the domain. A Windows 2000-based or Windows Server 2003-based computer's preferred DNS setting should point to the Windows 2000 or Windows Server 2003 domain controller running DNS.
If you are using DHCP, make sure that you view scope option #15 for the correct DNS server settings for your LAN.
52.Do I need to point computers that are running Windows NT 4.0 or Microsoft Windows 95, Microsoft Windows 98, or Microsoft Windows 98 Second Edition to the Windows 2000 or Windows Server 2003 DNS server?
Legacy operating systems continue to use NetBIOS for name resolution to find a domain controller; however it is recommended that you point all computers to the Windows 2000 or Windows Server 2003 DNS server for name resolution.
53.What if my Windows 2000 or Windows Server 2003 DNS server is behind a proxy server or firewall?
If you are able to query the ISP's DNS servers from behind the proxy server or firewall, Windows 2000 and Windows Server 2003 DNS server is able to query the root hint servers. UDP and TCP Port 53 should be open on the proxy server or firewall.
54.What should I do if the domain controller points to itself for DNS, but the SRV records still do not appear in the zone?
Check for a disjointed namespace, and then run Netdiag.exe /fix.
You must install Support Tools from the Windows 2000 Server or Windows Server 2003 CD-ROM to run Netdiag.exe.
55. How do I set up DNS for a child domain?
To set up DNS for a child domain, create a delegation record on the parent DNS server for the child DNS server. Create a secondary zone on the child DNS server that transfers the parent zone from the parent DNS server.
Note Windows Server 2003 has additional types of zones, such as Stub Zones and forest-level integrated Active Directory zones, that may be a better fit for your environment. Set the child domain controller to point to itself first. As soon as an additional domain controller is available, set the child domain controller to point to this domain controller in the child domain as its secondary.
