I have recently deployed Exchange 2000, with the Exchange 2000 installation on one server (back-end) and an OWA 2000 installation on another server (front-end). I have implemented SSL on the OWA 2000 server, and it is working fine (ie I can successfully logon to test accounts with OWA via https:\\servername\exchange
). Additionally, I wanted to force SSL encryption from a user's http request - the Force SSL Encryption instructions in KB279681 are not working. No matter what combination of changes I have attempted, when I use http:\\servername\exchange
I get the standard 403.4 error.
I have successfully implemented the instructions in KB279681 on our existing messaging system, Exchange 5.5 on Windows 2000 Advanced Server using SSL, and forcing SSL encryption is working fine on the existing messaging system.
So far, I have tried:
1. Recreating the owahttps.asp document
2. Copying the functioning owahttps.asp document from our Exchange 5.5 system to the OWA 2000 system to see if it works (it doesn't)
3. Applied owahttps.asp to both the Default Web Site\custom errors and Exchweb virtual directory\custom errors on the OWA server.
The properties pages match up closely enough from the old system (Exchange 5.5\Windows 2000 Advanced\IIS 5.0) to the new system (Exchange 2000\Windows 2000 Advanced\IIS5.0) - any possible conflicts or problems from the properties pages are not readily apparent.
Has anybody resolved this problem before?
