For those companies considering an upgrade to Microsoft Windows Server 2008, it is very important to understand how DHCP and DNS work together to power Windows Server 2008.
No that there is a difference in how Set-DNSServer Resource Record works compared to the ADD command.This one requires that we get the record, modify the IPV4Address field, then use it to replace the old object. You can easily modify this script, so that you can pass the DNS server name from the CSV file (updating lots of records on multiple DNS servers) or updating multiple record type (A Records, CNAME Records). Text explanations are almost useless, instead see the examples below which, hopefully, make the DNAME RR functionality more evident.The DNAME is already a pretty difficult RR to understand and master, if it is used with a wildcard (*) it could easily create such a mess that not even your mother could fix it.Also, make sure your DNS has the correct forward and reverse entries.

Under Windows NT, DNS was static and had to be manually altered to make changes.
With the advent of Windows 2000, many administrators were elated to hear that it contained a new feature called Dynamic DNS (DDNS).
When a DHCP server is added to the Dns Update Proxy group, its records aren't secured, meaning that other DHCP servers can update the records.
In additon, hosts can change the records and then become the owner of the record.
What this means in practice is the following: This means the DHCP server computer account will own certain records in DNS, such as the PTR records and even some A records for older hosts.
