Research direction

Start by reproducing the three executable outcomes on Windows 10 with executables mounted from the server using the alternate credentials. Compare successful runs with the two reported errors, including administrator-marked executables and ASCII-only paths; done means identifying a consistent cause or a documented limitation and its affected cases.

Written by the indexing model from the issue text.

Description

My server side has a bunch of exe files owned by X and permissions 755. I mount them using another user credentials (let's call it Y) into a windows drive letter.

In windows I can see all files without issues but when I execute files I get three outcomes:

  • program runs successfully
  • failure 1
  • failure 2

failure 1:

failure 2:

I'm not able to see any pattern on those errors, but here there are some clues:

  • the same folder can contain executables from the 3 categories
  • when the icon of the executable has the blue-and-yellow shield mark (the icon you see when right click -> run as administrator), it will give me the failure 1
  • I can get failures 1 or 2 even when the full path and file name are 100% ascii chars (no spaces or any other weird char)

All this happens under Windows 10 latest updates applied.
