We have an exchange 2003 front end server and 3 back end 2003 servers, all are running windows SP1 and exchange SP1. All are Windows 2003 Standard Editions except the newest back end which has been built with Enterprise edition. Currently we can log onto our mailboxes via OWA on the standard edition but the enterprise one just doesn't generate the page correctly. We can log into the enterprise one directly (not via front end) and get access to the mailbox with no problem but when accessing the same mailbox via the front end server it doesn't work (the page attempts to display but is very 'old' looking as if you were using something like netscape4) and just says loading. We thought this implied that there was an issue on our firewall not allowing everything through properly but our firewall people tell us that the enterprise server is in all the same groups as the standard one so the allowed traffic should be the same for each server. Obviously the fact that this is an enterprise version is the major difference but I haven't been able to find anything that says that this type of configuration shouldn't work. Does anyone have any ideas as to why it might not be working?
