OWA (Exchange 2003) - Forms based authentication - How to remove the need for the users to type the domain when they logon


We run

Exchange 2003
OWA 2003 / IIS6
Outlook 2003

We would like to have our users to have access to OWA without having to type the domain name. Is there any way to acomplish that?

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Open IIS > Right click OWA directory >  Directory Security > Authetication and Access control > Check .Net Passport Authentication and select the domain.

After this user will not have type the domain while login through OWA.

Sorry, check Basic Authentication and not .Net Authentication - Rest every thing same.

I have tried amitkulshrestha and azeempatel but it does not seem to work all the time. If the users try the username and password sometimes it works and sometimes it does not allow them to authenticate. If they use the domain name\username then it always works fine.

The OWA server is not joined to the domain and sits on the DMZ.

I have found the following article but I am not sure if this is what we are looking for.


Any help? Thanks

Hi llarava,

I was about to post you the same article. I suggest you to give a try, if you have any test lab...test in that first before going to prod. Please take IIS backup in Prod, in case you face any issue, backup will help you to revert back to old settings.
