We just finished upgrading from Windows 2000 / Exchange 2000 to Windows 2003 / Exchange 2003. I’ve downloaded and installed OWA Admin, but I cannot seem to get it to work. When I open the web page, either from the Exchange 2003 Server or from a workstation, I get prompted for my credentials. Once I log in, I get http error 404, the page could not be found. I’ve looked in IIS, and the virtural directory was created and points to the correct folder on the hard drive.
Can somebody tell me what went wrong, and how to fix the problem?
