Odd. I tried what you said--complete with tabs instead of spaces--and it doesn't work.
This is so I see across the top
Date Time Priority Hostname Message
and under Hostname, I see the name of the device and not the IP address.
I've also gone into setup and turned off DNS Resolution (as I said, our networking devices aren't listed there anyway), including any name resolution and caching.
Between edits of the StaticHosts.txt file and testing, I stopped the service and closed the window. Then when that didn't work, I tried editing the file and settings, stopping the service, and then restarting the machine with the service stopped (it's Startup Type is Automatic). This to no avail.
Any ideas what's wrong?
