After installing Sametime 11.6 IF2, i discovered that the entire proxy service will not start at all. In the localhost log you can see the following warning, over and over again. After opening a support ticket, HCL discovered a problem in the code. It seems like Sametime 11.6 IF2 needs a configured meeting server in the config.
