Running isa 2006 standard. Installed own created Certificates. Made sure that my own root CA is in the local computer's Trusted Root CA certificate store and that the certificates which will be used are in the local computer's Personal certificate store. However, when trying to select a certificate for SSL publishing, it shows a red cross and says: invalid certificate.
I am able to publish exchange through http, but that is not what we want.
Thank you for your reply. I tried to add the certificates again, so the one I want to use and the root certificates. Installed them in the Trusted Root CA store. ISA still wo'nt take it as a valid certificate. When I look at the certificate, and the path in the certificates MMC snap-in, it shows me that this is a valid certificate.
I don't think the certificate that you've got is right then for the ISA server. try creating a certificate from the exchange server IIS and give it the name of your external address. Then export the certificate and copy it to ISA see if that works.
