Thanks @AaronClark. That pointed me in the right direction, but the situation is a little different. Since the server is in my house, and Comcast rules say you can't run a web server on a home connection, I have IIS bound to another port besides 80, and have the router forward that port to that VM. I did not set that up on this VM until after I installed CRM. The IIS part of CRM works on either port, but the Tomcat stuff only works on port 80.
Does anyone know where the configuration file for the handoff from IIS to Tomcat is?
