I tried it a couple of months ago, went step-by-step through all the tutorials, and it gave me that message. So, we decided to wait until we got our official certificate, and paid a little extra for them to install it. When they installed it, they followed the exact same procedures, and it worked perfectly. Before they finished, I tested everything out, and it worked exactly how it was supposed to. I tried again last week to set up another listener, and now it again tells me there is no certificate installed... I'm becoming a little paranoid... -----Original Message----- From: Ara [mailto:ara@xxxxxxxxxxxxx] Sent: Monday, March 21, 2005 00:53 To: [ISAserver.org Discussion List] Subject: [isalist] RE: Secure Certificates http://www.ISAserver.org Did you export the certificate to pfx file or just a simple copy? I had some problem like this as I made a mistake importing the file. It was showing up on certificate list but wasn't able to be imported for owa. regards
