Currently OWA works internally and externally when I access the Backend server. It's Exchange 2003 SP2. Self Assigned Cert, SSL enabled. All works great... until I spun up a 2nd server to act as a Front-End Server. It's also Exchange 2003, SP2 and has a self assigned cert installed and is using SSL (Forms Based Authentication). The problem now is that if I point to https://myfrontendserver/Exchange, I got the OWA login screen fine, but once I enter domain\username and password and press login, I get an error -
HTTP Error 403.4 - Forbidden: SSL is required to view this resource.
Internet Information Services (IIS)
But I AM using https in the URL! If I try login to the backend server, I can login without a problem. I'm not sure where the problem is. I've checked the setup in IIS and ESM for both Servers and they are practically the same - except the certs - which are understandibly different. I am not sure though if I need a cert for the backend server anymore. Do I change the config of the backend server now that there is a frontend server? OR is all the config supposed to happen on the Frontend server? Does anyone have a "Best Practices" doc on how to set this up?
I have a separate server for GC/DNS
Thanks for any help, I've spent days working on this. Help for a new member will be greatly appreciated.
