TECHNOLOGY IN THIS DISCUSSION Join the Community! Creating your account only takes a few minutes. Join Now Details: This morning I rebooted our exchange server and proxy server had a issue where I removed the teaming on a pair of nics on our HP exchange server. The HP network config utility crashed and locked up my nic configurations and caused some down time... Eventually got that resolved and reconfigured the servers static IP again, etc. All is well, our desktop users outlook connects and everyone is happy. Problem is I found out every person logged into our proxy server error 3 terminal servers is unable to open outlook. What happens: User launches outlook prompts for password user enters password user gets error: "There is a problem with the proxy server's security certificate. The name on the security certificate is invalid or does not match the name of the target site mail.domain.com. Outlook is unable to connect to the proxy server (Error Code 0)" You can either repeat the process into a loop, work offline, or cancel. Work offline opens outlook and then says it cannot load any of the directories. it then closes outlook. How was this working for months and now there is a problem? The certificate: Our exchange server has a SAN cert where the common name is filter.domain.com. This is so we could use it with our sonicwall appliance and the thing is pretty finicky so we gave it the Common name. The altnernatives are: mail.domain.com
