What does "Disable Recursion" in DNS mean? In the Windows 2000/2003 DNS console (dnsmgmt.msc), under a server's Properties -> Forwarders tab is the setting Do not use recursion for this domain. On the Advanced tab you will find the confusingly similar option Disable recursion (also disables forwarders). Recursion refers to the action of a DNS server querying additional DNS servers (e.g. local ISP DNS or the root DNS servers) to resolve queries that it cannot resolve from its own database. So what is the difference between these settings? The DNS server will attempt to resolve the name locally, then will forward requests to any DNS servers specified as forwarders. If Do not use recursion for this domain is enabled, the DNS server will pass the query on to forwarders, but will not recursively query any other DNS servers (e.g. external DNS servers) if the forwarders cannot resolve the query. If Disable recursion (also disables forwarders) is set, the server will attempt t...

Describe the importance of DNS to AD. When Microsoft began development on Active Directory, full compatibility with the domain name system (DNS) was a critical priority. Active Directory was built from the ground up not just to be fully compatible with DNS but to be so integrated with it that one cannot exist without the other. Microsoft's direction in this case did not just happen by chance, but because of the central role that DNS plays in Internet name resolution and Microsoft's desire to make its product lines embrace the Internet. While fully conforming to the standards established for DNS, Active Directory can expand upon the standard feature set of DNS and offer some new capabilities such as AD-Integrated DNS, which greatly eases the administration required for DNS environments. In addition, Active Directory can easily adapt to exist in a foreign DNS environment, such as Unix BIND, as long as the BIND version is 8.2.x or higher. When Microsoft began development on Active...

Network Address Translation ( NAT ) In Routing and Remote Access Service (RRAS), NAT can be used to provide basic Internet connectivity for small offices or home offices. NAT translates IP addresses and associated TCP/UDP port numbers on the private network to public IP addresses which can be routed on the Internet. Through NAT, host computers are able to share a single publicly registered IP address to access the Internet. NAT also offers a number of security features which can be used to secure the resources on your private network. The NAT service is integrated with the router that changes the information of the originator in packets prior to them being forwarded to the Internet. NAT can be configured through a demand-dial interface where the connection is only established when the client specifically requests the connection; or through a persistent connection which is a permanent connection that remains open all the time. RRAS IP packet filters can be used to restrict incoming or o...
