SQL Server Network Configuration node missing from Configuration Manager after install

I have a server running Windows 2012 R2 Datacenter 64-bit. I was using SQL 2016 RC3 with no issues and I want to replace it with the RTM build we have from MSDN. After uninstalling RC3 and then installing RTM, I was unable to connect remotely to the server. Upon inspection, I see within Configuration Manager that there is no node for "SQL Server Network Configuration". The 32-bit versions are listed, and TCP/IP is enabled. How do I get this missing node installed? I have started the SQL Browser service and attempted to repair the 2016 installation. Nothing seems to revive this missing component. I find interesting that there are pieces of the RC3 and RTM installs left behind that I can't uninstall. I'm not sure if this is relevant. I followed Microsoft instructions on uninstalling SQL Server so I feel like I've done everything right.
