New SSL Cert - OWA + Internal resources on Server stopped working
We requested SWGFL to get us a Multi-Domain SSL Certificate from TERENA enabling us to be able to move to Live@Edu. So, I generated a Cert request from our Server (I backed up and removed the old Cert 1st), then unfortunately OWA and other internal services on the Server stopped working (Internet Explorer cannot display the webpage). As several important services had stopped working I emailed in the request for a new Cert then cancelled the request on the Server. I then re-imported the old Cert which got everything back working again.
Fast forward to today and I received the Cert via Email and went to install it. Again I removed the old Cert, placed the new Cert in the Trusted Root CA and Personal Cert store then assigned the new Cert to the desired Default Website in IIS 6. I checked OWA and I get the Internet Explorer cannot display the webpage error message. Same for all other services.
Both Certs have been issued to "mail..sch.uk" but only the old one works correctly. What have I done wrong?
We are using Server 2003 and IIS 6.
