OpenFile error with VAL_TRUNCATE

[ElectroLund]

I have a function which opens a file located on a local network.  I intend to rewrite all the contents of this file each time opened.  This application is the only writer to the file.

fileHandle = OpenFile(fileName, VAL_WRITE_ONLY, VAL_TRUNCATE, VAL_ASCII);
WriteLine(fileHandle, "some text", -1);
CloseFile(fileHandle);

On one of my stations, I regularly see the OpenFile fail with an error code 5, "File exists".

This is some sort of permissions issue?

UPDATE

This same station has started getting other network-related issues, so I replaced the PC.  Problem has gone away.
