I have a feeling it's the DNS cache. &nbsp;Can you give a try two things on any workstation:<br />
<br />
1. &nbsp;Try flushing the dns &quot;ipconfig /flushdns&quot; from the command line first? &nbsp;Then test again.<br />
<br />
2. &nbsp;Failing that then stop the dnscaching &quot;net stop dnscache&quot; ... also from a cmd window and leave it stopped. &nbsp;Now try again the nslookup/browse again.

I have a feeling it's the DNS cache.  Can you give a try two things on any workstation:

1.  Try flushing the dns "ipconfig /flushdns" from the command line first?  Then test again.

2.  Failing that then stop the dnscaching "net stop dnscache" ... also from a cmd window and leave it stopped.  Now try again the nslookup/browse again.

I setup a forwardzone domain.com with www,domain.com forwarding to external IP and crm.domain.com forwarding to internal IP (same server/dc). &nbsp;Browsing from the server resolves correctly, but browsing from local PCs in the domain do not. nslookup on PCs shows external ip of domain.com and crm.domain.com. It appears DNS on the DC is not being seen by client PCs; rebooting PCs doesn't help. Probably missing something simple... Thoughts?

Local DNS forwardzone not seen by clients?

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

A personal computer is a general-purpose computer whose size, capabilities and price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer time-sharing models that allowed systems to be used by many people, usually at the same time. Personal computers may be connected to a local area network (LAN), either by a cable or a wireless connection, and through that to the Internet. A personal computer may be a laptop computer or a desktop computer running an operating system such as Windows, Linux or Macintosh OS.
