I recently installed a new Domino server. Not an upgrade, but a scratch install. As expected, everything went smoothly. Until I started up the server. Once I started the server, I noticed the following message: HTTP Server: Using Web Configuration View HTTP Server: Unable to read httpd.cnf HTTP Server: Shutdown I hit the web and came up with this IBM technote, "Httpd.cnf deleted during Domino server upgrade." . But I didn't do an upgrade. It was a fresh install of Domino 8.5.1, but low and behold, that was the issue. I didn't install "Web Services Data Files" originally, but did in fact need them. I went back, re-ran the installed and selected it. The HTTP server now starts. Another lesson learned.
