This chapter contains a large number of tips and practical guidance directly from the Office Communications Server 2007 product, support, and consulting teams. When working through a problem, start with the guidance provided at the beginning of the chapter: attempt to simplify the scenario and gather as much information as possible about what is occurring. Look at event logs and trace logs from the client or server, validate network connectivity, and validate that servers are operational and configured as expected. Use of the Validation Wizard is very helpful in this regard, and many problems can be found easily before they are actually encountered.
