Outlook Web Access logon failures

I am having Outlook Web Access (OWA) logon failures for all clients except those with administrative permissions. My environment is 65 users, one Windows 2000 domain, Exchange 2000 behind a firewall, all service packs and rollups are current. Exchange is rejecting the password for non-admin types. How do I get my clients, especially those off-site, reconnected?
Make sure you have an IUSR account in your Active Directory. Also, check your Exchange server permissions for the IUSR account.

Solve SQL Server permissions and authentication problems For the past two weeks I've been trying to resolve a permissions problem, an authentication problem, or both. I've run out of ideas of where to look. Here is what I have: (1) SQL Server 2005 on a Member Server (2003) (2) I'm running Visual Studio .NET 2005 on my work station. (3) I can access the SQL Server data from within my .NET project. (4) If I access the website from outside my .NET project, I get Login Failed for user NT_AUTHORITY/NETWORK SERVICE. This happens on any PC and even the member server that houses SQL and the Intranet site IIS. (5) The reason I think I have a permissions problem is because of the behavior of two seperate test projects. Project #1 uses PROFILES to save state. When the program gets to this line of code, the Login Failed message appears. In project #2, I'm not saving state. But when the code attempts to gather data into a dataset, the program halts with the Login Failed message. Can you give me specific instructions on where to look and what to try?
