Dear sirs, after battling to configure share point services and configurinf IIS in sbs 2003 i can not longer access exchange 2003 webmail not even localy.Buti can send and receive emals throught outlook. . The error i receiveisHTTP 500 internal server error. My question is how can i reinstall only the webpages of the web mail with their default configuration .

Please check the following: Do we have FBA (Form Based Authentication) enabled? Check the same under Exchange System manager>Name of the server>protocols>HTTP>Exchange Virtual Server's properties, then settings. Is there any certificate installed? Try to disable the FBA, and then try if you are still facing the HTTP 500 error? Note= After you disable FBA, please do an IISreset Check the authentications on the exchange v-dir, we should have basic and integrated only. Also check the apppool linked with the exchange v-dir, exchange application pool should be linked with the exchange v-dir Also try to browse the exchange v-dir from the IIS Manager and check if it works fine or you get the same error? And also try this article http://support.microsoft.com/kb/883380
