Explanation

When server certificates are signed by a private (internal) Certificate Authority, Windows clients will not trust those certificates by default because the private CA is not included in the OS trust store. To resolve certificate errors on Windows machines, the private CA's root certificate must be imported into the 'Trusted Root Certification Authorities' certificate store. This tells Windows to trust all certificates issued by that CA, which resolves Jabber's SSL/TLS handshake errors. Importing into the 'Personal' store only applies to your own identity certificates; the 'Intermediate Certification Authorities' store is for intermediate CAs (not root CAs); and the 'Trusted Publishers' store is for Authenticode software publishers - none of these resolve server certificate validation failures.
