-- After logging onto OWA I am getting the error message 'HTTP/1.1 500 Internal Server Error' -- I appear to be logging on to the server, because the left side of the OWA screen shows my inbox, contacts, etc. The large right window displays the error- HTTP/1.1 500 Internal Server Error and I am unable to view mail items or contacts, but the calendar view is working. This error occurs when logging on from internal as well as external clients. My clients are win2k and win98 using assorted versions of IE. I do not have friendly IE error messages turned on. Browsing locally on the box fails with the same error. My server is a front-end Exchange 2000 sp2 box that relays incoming/outgoing mail and supports SSL connections to OWA. I am using the IIS lockdown tool. The box is on the inside of a firewall only allowing port 25 and 443 connections to the server. ftp, telnet, etc services are disabled. wwwpub and the proper exchange services appear to be running. There have been no recent changes to the server (this was working last night) The server has been stable. neither event logs or iis logs are being particularly enlightening This error is so general I am having trouble finding anything relevant on Google Web or Groups. Any help would be appreciated. Thanks in advance.
