We recently installed MS Certificate server on one of our machines and regenerated the cert that OWA was using so its from MS Cert Server instead of the previous cert which was from Novell Cert Server. Since that time OWA is so horribly slow when accessed through the firewall, which it wasn't using the Novell Cert. Internally its normal speed, but externally it can take 3 minutes before the login screen even shows up. Any ideas? Thanks.
