I've recently setup an Exchange Server behind our comapny firewall and am presently configuring it to allow Outlook Web Access for users who wish to check their email from outside the company WAN. The port allowing access through the firewall is working correctly and brings up the login asp page for OWA, however a logon box appears asking for usename, password and domain. When you enter your information, the logon box reappears after a few seconds and prompts for a password again. If you enter your password a further time, the window then goes white with the address bar url address looking like it has authenticated you. The access to this service is via https and we use SSL/clear text authentication.
Attempting to access the same service over the LAN/WAN (ie not through a dialup connection) takes the user straight into their inbox. The url access for this is also done via https but to the servers internal IP.
What is puzzling me is why it's asking for a domain logon account to access email?
