Short filenames can be painful

So I migrated data on a Windows 2008 file server this weekend and it seemed pretty straight forward until I checked services and found the patching proxy service wouldn't start. The services uses squid proxy and it turned out by checking the log file that it uses the 8.3 dos short filenames for paths to the config file. I did dir /x and found two program file paths, Program Files (x86) - PROGRA~1 and Program Files - PROGRA~2. They must have switched shortname when copying, I can only assume the x86 folder was originally created first on the server. It was pretty annoying but thankfully pretty easy to switch them around using "fsutil file setshortname." I can now enjoy the rest of my sunday!
