I'm having an issue with Microsoft Exchange Control Panel.
I have 2 servers with Exchange installed, both have the Client Access role, however only one has the Mailbox and Hub Transport roles. When I log in to the server hosting the Exchange Mailbox and Hub Transport roles, I am able to access the ECP webapp no problem. However, on the Internet-facing server (with only Client Access) I get the following error:
