Posted July 8, 200816 yr On our network, we can connect xp machines to our exchange server using rpc over http. However, we cannot connect Vista machines to the same server using rpc over http. We get the following error message. "There is a problem with the proxy server's security certificate. The security certificate is not from a trusted certifying authoritty. Outlook is unable to connect to the proxy server domain.com (Error Code 8)" What are the differences between Vista and XP in connecting to the exchange server over http?
