MrsLop -
Sorry about that.
What I was trying to get out of you was whether or not you had customized the installation at all because it sounded to me like the Apple Enet extension never got loaded up, thus the problem you're seeing.
A couple of things:
First, check in System Folder > Extensions (Disabled) and see if there's any mention of it there.
If not, then you may consider running the 8.6 install again and when you get to the point in the install where you can choose "Customize", click on that button and then I think the list you want is under the MacOS set. There should be a section underneath it in the same window that lists a header called "Networking", with an expandable checkbox. Click on the checkbox to expand it, and scroll down until you see "Apple Enet". Make sure it's checked and then proceed with the reinstall.
Once that extension's installed you should be good to go.
As far as DHCP, well........chalk that up to an overzealous TSer.
We can deal with that another time.
Hope that helps.
Chris
