IT's a self-signed certificate generated by SBS. In IE7 you have to jump through some hoops to install one. Click on the Certificate Error next to the address bar. View cert. Click install. Click yes, I want to install it anyway. Normally the cert is then installed correctly. In the case of these laptops, you still see the cert error near the address bar. If you select more information, it pops up a box that says there is an address mismatch. I would believe it except I have this same cert, following the same procedure installed on my laptop. Just had a thought. Could this be a admin rights issue? Hmmm -----Original Message----- From: isapros-bounce@xxxxxxxxxxxxx [mailto:isapros-bounce@xxxxxxxxxxxxx] On Behalf Of Jim Harrison Sent: Monday, May 07, 2007 11:39 AM To: isapros@xxxxxxxxxxxxx Subject: [isapros] Re: RPC over Http What he said, plus can you elaborate on "..address mismatch error when they attempt to install the certificate.."? This sounds more like a connection, not an installation error? -----Original Message----- From: isapros-bounce@xxxxxxxxxxxxx [mailto:isapros-bounce@xxxxxxxxxxxxx] On Behalf Of Thomas W Shinder Sent: Monday, May 07, 2007 7:58 AM To: isapros@xxxxxxxxxxxxx Subject: [isapros] Re: RPC over Http Hi Amy, Are you installing the certificates via the MMC and into the machine certificate store? Also, make sure the CA certificate is installed in the Trusted Root Certification Authorities.

We're setting up RPC over HTTP so I need to install the certificate on the laptops. The cert installs fine onto my Vista IE7 laptop but does not install on their XP IE7 laptops. They are getting an address mismatch error when they attempt to install the certificate. Since they same certificate installed without error for me, I'm not sure where to look for the problem. It seems like it has to be something on the laptop rather than an issue with the cert. I have looked for old certificates on the laptops. Didn't see any. Any other ideas on where or what I should look for?
