Aside this,
your
VFP version
OS
Server OS
?

I run VFP 9SP2 / VFPA on a Win10/64 using SAMBA on a Linux, and the command runs perfectly well.
Try to create a file on the share, close, write, delete. First directly via Explorer, then via VFP IDE, for example MODI FILE, then via running EXE
Does the file possibly exist and is locked against change? Some servers are a bit lame if a file is closed and reused by other process. i have theis with a XLSX that close / open between different comps on high frequenzy, sometimes it's not closed the way it should be closed and stuck for a while as RO.
