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.

Also see:

I tried the registry edit mentioned here too but on my 8.1 OS it didn't 
seem to change anything.

You can use the pushd/popd commands - example:

Microsoft Windows [Version 6.3.9600]
(c) 2013 Microsoft Corporation. All rights reserved.

C:\Users\jlowe>lilypond x:\test.ly
GNU LilyPond 2.19.82
warning: cannot find file: `x:\test.ly'
fatal error: failed files: "x:\\test.ly"

C:\Users\jlowe>pushd x:\

I hope this helps.
