I've got a SBS2003 with OWA2003 on it, and up until yesterday if you went to either http://server/exchange
it would automatically redirect to https://server/exchange
This has stopped working. OWA still works if you manually type in https.
Also, the other http SBS sites seem to have stopped working too - SharePoint, ConnectComputer, Remote.
Everything did work until yesterday, and there's been no changes to the system. There's no errors in teh error log, no errors in the IIS website logs, but the requests for the site show up as 404 not found. When I look at the websites in IIS, all the required parts are still there (Exchange, exadmin etc etc)
