httpslidepdfcomreaderfullfinal-minicast-understanding-network-name-resolution 225
Name Resolution All communications between
computers and any other devices on a TCPIP networkare addressed using IPaddresses such asldquo192168152rdquo
Name resolution provides amethod of referring tocomputers by name instead of using network addresses
Windows has historically usedtwo separate naming
schemes host naming andNetBIOS naming Starting with the products
released at the time of Windows 2000 Microsoft hasbeen eliminating the need touse NetBIOS naming inMicrosoft networks

Host Name Resolution
DNS or the Domain Name Service providesname-to-IP address mapping enabling clients torefer to destinations by name rather than IP
addresses DNS has been the standard method of resolving
Windows Networking resources since Windows2000
The ldquohostsrdquo file provides local name resolutionfor TCPIP-based functions Located in ltsystemrootgtsystem32driversetc Can store any name-to-IP address mapping Contains 127001 ldquolocalhostrdquo mapping by default

Benefits of DNS
Scalable The service is appropriate for very large and very
small networks
InteroperableMicrosoftrsquos DNS server is RFC-compliant
Distributed DNS allows for the task of providing name-to-IP
address records for the Internet to be distributedamongst DNS servers eliminating the need for aldquomaster listrdquo catalog of all names

Important Terms Zone
A zone is a table of IP addressand name information used toanswer requests
More than one DNS server can store a copy of a zone for redundancy
Domain Unlike an Active Directory
domain in DNS the termldquodomainrdquo simply defines a
ldquonamespacerdquo Allows an individual to reservea section of the DNS namingstructure for use in creatingnew names
DNS domains are hierarchical

DNS Naming Structure
Becomes less specific as the name moves from left toright
Hostsubdomaindomaintopleveldomain ie wwwmicrosoftcom ()
There is a true top level least-specific domain in everyname called ldquorootrdquo represented by a dot that is nottyped
The first word of the name was traditionally the actualname of a host on a DNS network although a single IPaddress can be mapped to multiple names

DNS Client software Two types
Stub resolvers Built-in to all standard
TCPIP hosts
(computers) Capable of sending a
recursive request to aDNS server
Full resolvers
Built-in to DNS Serversand DNStroubleshooting toolssuch as nslookup
Capable of sendingeither a recursive or
iterative request

DNS Servers
Capable of storing IP address records for a zone Capable of answering both iterative and
recursive requests for records within zoneshosted locally on the DNS server ldquoAuthoritativelyrdquo
Capable of fulfilling recursive lookup requests on
behalf of clients Capable of forwarding a recursive lookup
request to another DNS server (a ldquoforwarderrdquo)

Types of Zones
Standard Primary Stores DNS records in a text file on the hard drive
Standard Secondary Retrieves a copy of the zone from another server and
uses the copy to answer requests Active-Directory Integrated
Stores zone information in Active Directory
Enables secure DDNS Stub zones
Retrieves a copy of the SOA and NS records fromanother server and uses the copy to refer lookupprocesses to the correct DNS servers
8152019 FINAL - MiniCast - Understanding Network Name Resolution
httpslidepdfcomreaderfullfinal-minicast-understanding-network-name-resolution 1125
Forward and Reverse Lookups Forward Lookup Zones
Store information for name-to-IP address lookups Use the DNS name hierarchy for organizing zones
Reverse Lookup Zones Store information for IP address-to-name lookups Use the IP subnet structure for organizing zones

Record Types
ldquoArdquo or ldquoHostrdquo records Simple mapping of a name to IP address Can be created automatically using Dynamic DNS
ldquoCNAMErdquo or ldquoAliasrdquo records Allows a name to be mapped to an already existing
name
ldquoMXrdquo or ldquoMail Exchangerrdquo records Identifies the name or names of SMTP servers
capable of receiving SMTP mail for the domain name
8152019 FINAL - MiniCast - Understanding Network Name Resolution

Record Types
ldquoPTRrdquo or ldquoPointerrdquo Records Used in Reverse Lookup Zones to provide name information
when queried for an IP address
Can be created automatically using Dynamic DNS ldquoNSrdquo or ldquoName Serverrdquo Records
Shows the names of DNS servers for a zone
ldquoSOArdquo or ldquoStart of Authorityrdquo record Stores configuration information for how the zone operates Accessed through the SOA tab of a zonersquos properties in
Windows Server 2003 DNS servers

The SOA Record The Start-of-Authority
ldquoSOArdquo record is a keyelement of DNSconfiguration on all DNSservers
The Windows 2000 andWindows Server 2003versions of DNS use aGUI for configuring SOArecord properties
Settings placed in theSOA determine behaviorsfor copies of the zone onall secondary DNSservers

Active Directory and SRV Records
ldquoSRVrdquo or ldquoService Locatorrdquo Records Used to store information about services needed for specialized
applications Used extensively by Active Directory authentication processes to
locate Domain Controllers and Global Catalog Servers
A separate zone called ldquo_msdcsltdomainnamegtrdquo iscreated to manage SRV records for Active Directory inWindows Server 2003 DNS
8152019 FINAL - MiniCast - Understanding Network Name Resolution
httpslidepdfcomreaderfullfinal-minicast-understanding-network-name-resolution 1625
Dynamic DNS
Allows clients to configure ldquoArdquoand ldquoPTRrdquo recordsautomatically
Can be used by serviceproviders to host a service onthe Internet without a static IPaddress
Can be used to create recordsfor all Active Directory domainmembers in DNS automatically
When used with ActiveDirectory-Integrated zonesDDNS may be secured so onlydomain members can createrecords

NetBIOS Names
Must be 15 characters or less
No case sensitivity
Often referred to as ldquocomputer namerdquo The ldquolmhostsrdquo file
A sample version is stored in
ltsystemrootgtsystem32driversetc with the name
ldquolmhostssamrdquo

WINS Server Replication
WINS is a multi-master
database
Two types of replication Pull replication
Configured to occur at
regular intervals
Push replication
Configured to occur after acertain number of changes
have been received

httpslidepdfcomreaderfullfinal-minicast-understanding-network-name-resolution 2125
Name Resolution Troubleshooting
Ping Pinging a target by name will attempt hostname (DNS) resolution first
then NetBIOS (WINS) resolution if NetBIOS is enabled Whenever name resolution is failing ping the DNS and WINS servers by
IP address to make certain they are up and running Check the DNS and WINS services to make sure they are running on the
servers Nslookup
Use to manually perform iterative lookups on DNS servers Type ldquonslookuprdquo at a command prompt to access the tool in interactive
mode Type ldquoserver ltDNS server name or IP addressgtrdquo to change the DNS
server being queried A wide variety of other functions available by typing ldquoHelprdquo inside an
interactive Nslookup command session NBlookup
Use to see if names are being stored on individual WINS servers More information is available at http

Benefits of DNS
Scalable The service is appropriate for very large and very
small networks
InteroperableMicrosoftrsquos DNS server is RFC-compliant
Distributed DNS allows for the task of providing name-to-IP
address records for the Internet to be distributedamongst DNS servers eliminating the need for aldquomaster listrdquo catalog of all names

httpslidepdfcomreaderfullfinal-minicast-understanding-network-name-resolution 525
Important Terms Zone
A zone is a table of IP addressand name information used toanswer requests
More than one DNS server can store a copy of a zone for redundancy
Domain Unlike an Active Directory
domain in DNS the termldquodomainrdquo simply defines a
ldquonamespacerdquo Allows an individual to reservea section of the DNS namingstructure for use in creatingnew names
DNS domains are hierarchical

Name Resolution Troubleshooting
Ping Pinging a target by name will attempt hostname (DNS) resolution first
then NetBIOS (WINS) resolution if NetBIOS is enabled Whenever name resolution is failing ping the DNS and WINS servers by
IP address to make certain they are up and running Check the DNS and WINS services to make sure they are running on the
servers Nslookup
Use to manually perform iterative lookups on DNS servers Type ldquonslookuprdquo at a command prompt to access the tool in interactive
mode Type ldquoserver ltDNS server name or IP addressgtrdquo to change the DNS
server being queried A wide variety of other functions available by typing ldquoHelprdquo inside an
interactive Nslookup command session NBlookup
Use to see if names are being stored on individual WINS servers More information is available at http

Active Directory and SRV Records
ldquoSRVrdquo or ldquoService Locatorrdquo Records Used to store information about services needed for specialized
applications Used extensively by Active Directory authentication processes to
locate Domain Controllers and Global Catalog Servers
A separate zone called ldquo_msdcsltdomainnamegtrdquo iscreated to manage SRV records for Active Directory inWindows Server 2003 DNS

Dynamic DNS
Allows clients to configure ldquoArdquoand ldquoPTRrdquo recordsautomatically
Can be used by serviceproviders to host a service onthe Internet without a static IPaddress
Can be used to create recordsfor all Active Directory domainmembers in DNS automatically
When used with ActiveDirectory-Integrated zonesDDNS may be secured so onlydomain members can createrecords
