We've developed our corporate intranet in MOSS on Windows 2003 and linked it to our active directory so that if you enter https://portal.ourcompany.local
from the LAN, you get through to the MOSS intranet, and are logged in to the portal automatically because we are logged in to our desktops.
Through MOSS, we have changed the FQDN of the intranet to https://portal.ourcompany.com
so that those out on the road can access it. Works fine externally with a logon popup shown for the user, but internally on the LAN where people log onto the ourcompany.local domain through active directory we'd still like them to be able to log in to https://portal.ourcompany.com
without getting the popup box.
By entering their details again they are taken to the portal but we'd like to omit this additional prompt. The DNS records have been changed so that someone on the LAN gets portal.proctorgroup.com resolving locally to the MOSS server.
How can we get rid of the additional login prompt for local LAN users?
