In 2003 and 2008  DNS is usually Active Directory integrated (a part of the AD database) and replication occurs during AD replication.  2000 DNS is not integrated with the AD and uses a client similar to UNIX systems to update from other DNS sources.

Do you have a specific question or problem.  If not, if you just search the web on "troubleshooting DNS" you can get a valuable understanding of the functioning o DNS.
DNS is replicated by domain controllers in the forest. Active Directory–integrated DNS is assumed, wherein DNS zone data is stored in Active Directory and is replicated to all domain controllers that are DNS servers or are DNS servers in the AD zone(s)...

However, do you have a specific question or issue in mind? Basically everything is handled through AD, Sites & services and Domains & trusts if you have any.

If it is a Active Directory integrated DNS then how frequently will replication take place, how does replication take place and how to monitor it.

This depends on how long it has been since the last time the DC, GC's and zones were last verified\replicated; should not take longer than 15 minutes by default but would usually be less.
This is between the servers... Workstations may need to be rebooted or at least have ipconfig /flushdns then ipconfig /registerdns run on them before they see any changes.
Oh, to monitor it would be to look at the system logs on the DNS servers and look at the DNS server log and the Directory Service logs to see who and when replication is occurring with.
if its active directory integrated DNS to see how often its going to replicate depends if the DNS servers are on the same site or on different sites, to discover exactely how often its going to take place go to active directory sites and services=> expand the inter-site transports=>and press on IP=> on the right panel right click on any site you want and properties=>you will see replicate every and here you can modified the replication time.
