Dhcp not updating dns server Dirty online chat rooms for cam2cam

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.In this post, you will learn how to configure DHCP to dynamically collaborate with DNS and WINS in Windows Server 2008.Under Windows NT, DNS was static and had to be manually altered to make changes.

To access this menu and configure DHCP for dynamic updates: When configuring DDNS, you can Pause the DNS service and change the zone type, as shown in Figure B and Figure C.

If you select Active Directory-Integrated, you can choose Secure only from the Dynamic Updates drop-down list.

If AD is not running, your choice is simply Yes or No to allow dynamic updates.

Now we can spice things up a little more by introducing WINS and WINS-R into the mix.

For the uninitiated, WINS resolves computer names to IP addresses (similar to DNS), and WINS-R provides reverse DNS lookups.

In addition to configuring DDNS, you can configure your DNS server to use WINS for name resolution.To perform this function, open the DNS console, right-click on your forward lookup zone, and select Properties (Figure D).Basically, DDNS, in conjunction with DHCP and Active Directory, can provide secure dynamic updates for your A and PTR records in DNS.For example, a client machine receives an IP address from DHCP and then DHCP automatically (as long as it is configured to support DDNS) passes along the host information for that machine to the DNS service.This feature alone can save an administrator a lot of valuable time.As you can see by the Properties sheet shown in Figure A, you have a number of options to consider when configuring DHCP for dynamic updates.
