Sorry this took so long for me to get back to you.

More research tells me that it is not lilypond that is at fault here
but Windows.

Windows cmd does not support UNC paths.

That should not be relevant, though. That at most limits the ability for the current working directory to be a UNC path, without first mapping it to a drive letter. But it really should not affect the ability to invoke LilyPond and pass in a UNC path for the input file. As an aside, PowerShell does not have the same working directory limitation, and you can cd to a UNC path as you wish.

But back to the issue, if LilyPond is ultimately calling CreateFile passing in the file path as specified in the command-line arguments, it should be able to open a UNC-based path providing there are no permissions issues. What I would suspect is some quirkiness with MinGW/MSYS and Posix paths such that LilyPond is not generating the correct API call.

As such, what would be interesting is to get a Process Monitor capture of the failing case. That way, we can see which specific file I/O calls failed and with which errors. Unfortunately, I no longer use the Windows version of LilyPond, so I cannot immediately test this on my setup without having to set up a VM first. If it is possible to run LilyPond in a portable mode without installation, then that would save significant time getting a test environment.

I am trying to double-click a .ly file that is in a network share. When I
do so, the following log file is created:

------------
# -*-compilation-*-
warning: can't find file:
`\\server\fgasper\my_docs\Scores\editions\conditor3-alt_lyrics.ly'
error: failed files:
"\\\\server\\fgasper\\my_docs\\Scores\\editions\\conditor3-alt_lyrics.ly"
------------

If I copy the file to my Windows desktop and double-click on it there,
everything works as normal.
