Why isn't DNS pointing to our server correctly?


We have an internally hosted email server, which our staff connect to through a web browser. When the staff type in the IP address of the server to connect to it, they are prompted with a login box which then diverts them to their email. (This is useful as some staff have more than one account). However, previously staff could use the URL webmail.domain.uk.com to get the same login prompt, but now the URL automatically obtains their credentials and logs them in, whereas the IP still gives the desired effect. To work around this, I created a DNS entry as follows:

Forward Lookup Zones:

Host : webmail
FQDN : webmail.walkden.uk.com
IP :

Reverse Lookup Zones:

IP :
Host Name : lh-whs-email.*domain*

These are the only two related entries for the email server I can find, and neither made any difference. Are any of them configured wrong, or are more necessary maybe?

Check the browser settings on the client machine.  In IE go to TOOLS - INTERNET OPTIONS - SECURITY.  Check out the settings for the Zones and see if your server name is in any of the Sites.  Check the Custom Level... for that Zone and see if Automatic Logon is set (it's at the bottom of the list).

Thanks robrandon

Your comment was really usefull and works a treat, the only problem is that we would have to do this on every machine in the school and there is 300-350 of them at least and that would be very time consuming.

Do you know of any way that we do this by using a setting in server 2003 and then let the changes filter down to the clients.


If the workstations are all domain members, I believe you can deploy the settings with a group policy.

If they are not domain members, you would probably have to provide a script to the users or manual instructions for them.
