I'm having a problem troubleshooting an error after the logon page for "Outlook Web Access" (OWA) for Exchange 2003. We are running Active Directory on Windows Server 2003 Standard. The OWA default logon page pulls up fine, I enter my "Domain\Username" account with password, and then I get a blank page stating "Unspecified error" with the OWA DLL file in the path. This happens both internally and externally to the network. My AD account is in the "Administrators" group. Has anyone ever experienced this before? We have a few hundred users all using Outlook 2003 connected to this Exchange 2003 box without problems, and I'd like to open this extra option up for users trying to access from home (though, after they would authenticate over VPN first). TIA !!
