Well i found, what is wrong. I have setup Two IP addresses. Because if I setup second OWA/ECB/OAB/AES. Without EWS, because EWS brings up local host binding, it mess the system. But if you do not use ews, it looks like, Exchange shell and EMC probably connect to both, or get response from wrong IP with no EWS, and then bring up 404 error. When I clean up second web site, and remove second IP, error is gone. It would be fine, if Microsoft published supported exotic configuration, so someone does not go in to a hole, that is not supported.
