Inserting an Address into our Internal DNS

Hi, Experts

I do not have alot of experience playing with DNS.. I've setup the basics and even that at times is luck.
Our ISP for our Hosted Exchanged needs me to add an entry to our DNS to allow autodiscovery.ourdomain.com to resolve to its IP so that our users can get Offline Address book into Outlook 2007/2010 instead of accessing their server each time we open our Global Distrubition list.. I am not sure where and how to add this to our DNS and I certainly don't want to mess with it blindly. Thanks in Advance

I am assuming your dns is on a windows box, go into dns open the forward lookup zone right click on the domain and choose new host (a or aaaa) Fill in the needed info click add host and you should be set.

You are going to want to make that entry into who ever is hosting your external dns information. This is more than likely whoever you are registering your domain names with, although not necessarily since some people register with company A and then let their hosting company run there dns for them if they are different.

When you run IPConfig /all on our workstations here at the office. our DNS points to our DC that is running DNS.. and the Help Desk tech at our Hosted Exchange ISP stated I would need to add it to our internet DNS so that we can ping it. Does that make sense.. he added it to my Hosts file and it worked, but stated putting it in the DNS itself would do the same thing for everyone

Yes usually your workstations point to your internal dns servers which in turn point to external name servers. If you want to be able to access this info only internally then you can just add it to your internal dns server. If you have users who use Outlook outside the office than you are going to want to add it to your external dns so it is seen by anyone at anytime.

Believe they have added it to the External DSN under Public.as our remote users can get it. now how do I add it to my internal DNS without messing it up by adding to the wrong place or something like that

Ok.. done that.. now how long does that take to become effective or is it instant like Hosts files?

When done on an internal server it is instant.
