Is it possible to create Dynamic DNS server on Server 2008? Is any alternatives, if not?

Hi,Windows 2008 DNS server is a dynamic DNS server , it has two modes to be configured:1. accept only secure dynamic updates where only Computer Joined to the domain can dynamically register and update DNS server records.2.all non secure update where any DNS client can register and updateDNS records.Many Other DNS servers also support Dynamic update suchDNS implementations that use the Berkeley Internet Name Domain (BIND) software.http://support.microsoft.com/kb/246804http://technet.microsoft.com/en-us/network/bb629410.aspx#1Hikmat Kanaan Amman-Jordan MCSE
