Do I need a Certificate? RRS feed

  • Question

  • Sorry, its the first time I've ever done a clean install of Communications Server and I'm using version 2007. All we're looking to do is have internal messaging within the company and within the actual building. Do I need a certificate for that?

  • Hi,

    OCS, by default, requires a cert for all client/server & client/client communications. So you should have a cert. It can be a cert that you issue from your own internal CA, but it should still be a cert.

     

    However, you can reconfigure OCS to use TCP rather than TLS. This will allow you to communicate without a cert, albeit unsecured communication. MS doesn't recommend this. It is possible, though.

     

    Regards,

  • If you are simply looking to do web conferencing with a couple remote friends I'd suggest using a free service like Windows Live Messenger.  Setting up OCS to run in a 'home' network behind a single dynamic IP from a standard ISP is difficult to impossible depending on the feature set you need to use.  Or are you planning tin install this in a corporate network and then remotely access it from home?  Some more details about what you are attempting would be more helpful.
