OWA Outlook Web Access 2003 Logins will not work

We just installed a Windows 2003 Server and Exchange 2003 server.  We can open Outlook Web Access for only the Administrator account and none of the others.  I am moving mailboxes from an old Exchange 5.5 server, one at a time.  I try to login as each one and it keeps asking me for the username and password.

It will ask for the username and password 3 times, I have used the username then password, then I tried DOMAIN\username and password.  Only Administrator logs on perfectly.

I have tried adding Domain Users to the Internet group.  I have tried just adding a brand new mailbox on the 2003 server to see if it is a migration issue.  But it even the brand new mailbox will not open via OWA.

I can open all mailboxes seemlessly with Outlook on computers all over the company.

Any help is appreciated.

Is the Exchange Server also a DC?

It looks like a permissions issue.  I would ensure that the users have access to the EXCHWEB folder and all folders below this.

It is probably a combination of IIS configuration and NTFS permissions that got out of whack on your Exchange server.  Here are a couple articles that explain the process of fixing it.

I tried those and it ended up not working at all.  Then I installed Service Pack 2 for Exchange Server 2003 again and it fixed everything perfectly.
