How to synchronize manually a client computer to a domain controller?
Windows 2000 (Win2K) and later computers in a domain should automatically synchronize time with a domain controller. But some times you may get a situation to synchronize manually. To manually synchronize time, open a command-line window, and run
Net stop w32time Run
w32time –update Run
Net start w32time
Manually verify the synchronization between the client computer and a domain controller. Also check the System event log to ensure that the W32Time service has not logged additional error messages.

How to configure the DNS?
Open the DNS Console
Then you will find there
Forward Lookup Zone
Reverse Lookup Zone
Note: If you have selected create automatically zones during the setup, then it creates the root zone and domain zone under forward lookup zone.
If no zones are there under forward lookup zone first create root zone then create domain zone.
How to create a zone?
Right click on forward lookup zone ènew zoneè
Active Directory Integrated
Select any one of above.
Note: The option Active Directory Integrated Zone is available on when you have installed the Active Directory; if you have not installed Active Directory the option is disabled.
Note: If you want to select a Secondary zone u should have already a primary zone or Active Directory Integrated zone.
Give the DNS name
Note: If you r creating a root zone then just type in the name box “.” (only dot)
Then click Next
After creating the root zone then create another zone with Domain Name
Right click on Forward Lookup zone è New zone èActive Directory Integrated (you can choose any one) èDNS Name [___]èNext èFinish
Right Click on Reverse lookup zoneèNew zone èType Network IdèNext èName èFinish
Right Click on zone èselect Create associate Ptr (pointer) record èNext èfinish

Where to create the primary, secondary, Active Directory Integrated zones?
If you want to create an Active Directory integrated zone, the server must be Domain Controller.
If you want to create the Primary DNS, you can create on Domain Controller or Member server. But if create on member you could not get 4 options under the domain which are meant for Active directory.
You can create Secondary zone on a Member Server or on a Domain Controller. There is no difference between them.
What are the advantages with Windows 2000 DNS? Or What are the features of Widows 2000 DNS?
Supports SRV (service) records
Supports Dynamic Updates
Supports IXFR (Incremental Zone Transfer)
Explain each one of the above?
In windows 2000 Domain you need to have a DNS server to find different services. The SRV records identify these services.
When you enable the Dynamic updates, all the records in the zone are automatically created. As we add a computer to the domain, as we add a Domain controller to the domain the corresponding records are automatically created. I.e., you need to create a record in the DNS zone manually to identify those computers or services.
When an update is made in the Master it has to be replicated to the Secondary. Previous we used to transfer the entire zone (which is called AXFR (entire zone transfer)). But with Windows 2000 domain we transfer on the records that have been modified. This is called IXFR (Incremental Zone Transfer).
We get the security with Active Directory Integrated zone. We can set permission on Active Directory like who can use and who can't use the DNS. And also we have Secure Dynamic updates with Active Directory Integrated zone. By this only specified computers only can dynamically update the records in the zone.
Nslookup (and all interactive mode commands)
Note: A best strategy of using DNS in corporate network is use two DNS servers. One is on internal network and another one is between two firewalls. For more security keep the zone as secondary in the DNS server which is between firewalls.
How we make more available our DNS?
By adding more tuple servers or By windows 2000 clustering.
What is the purpose of forward lookup?
It resolves the Host names (Friendly Name) to IP addresses
What is the purpose of Reverse lookup zone?
It resolves the IP addresses to Host names
What is the difference between Primary zone and Secondary zone?
Primary zone has read and write permissions, where as Secondary zone has read only permission.
Note: Secondary zone is used for Backup and Load balancing.
How to check whether DNS is working or not?
Type the command “nslookup” at command prompt
Then it gives the DNS server name and its IP address
What is Dynamic Updates in DNS?
Generally we need to create a host record for newly joined computer (either client or Member server or Domain controller). If you enable dynamic Update option, then DNS it self creates associated host record for newly joined computers.
How to get Dynamic Update option?
Right Click on any zone è properties è on General tab u will get Allow Dynamic Updates?[_Yes/No/Secure Updates]
Note: Put always Dynamic Updates “YES”
Note: If it is Active Directory Integrated zone you will get above three options.
But if it is Primary or Secondary zone you will get only “YES/NO” (You won’t get secure updates)
What is name Resolution?
The process of translating the name into some object or information that the name represents is called name resolution. A telephone book forms a namespace in which the names of telephone subscribers can be resolved to the phone numbers.
What is BIND?
What are the ports numbers used for Kerberos, LDAP etc in DNS?
