Disable OWA Network Prompt

[rmango]

Hi! I have set-up IIS/OWA with Exchange Server 5.5 SP3 together on a computer,
enabling NTLM authentication in IIS. Our users access OWA via the internet.
We added some code on logon.asp so that the user's mailbox name is automatically
entered but my problem is the network prompt (Name, Password, Domain) comes
up the first time. Can we avoid this first time prompt? We want our users
not to enter their mailbox name/pwd on the prompt on their first logon.

Hello,

you have to enable Annonymous authentication on your exchange virtual directory
or Default web site (if you have configured default web site to point to
"webdata\usa" folder". This is in addition to NTLM authentication.

Try this out.

Thanks.
Vinayak.
