Thanks for replying. I tried this just now and it does not throw an exception, and the folder is such that I cannot create a text file in it (via File Explorer). I was thinking I will just have to do a trial file create (like the solution below), but I was hoping there was a more sophisticated method.

Also, I neglected to mention in the original posting that this thread-spawning code and the thread code itself were borrowed from a web application that has always worked well to send files to our test equipment.

Thanks for your response. But can you explain how it works 100% of the time on my Server 2012 R2 and 10%-50% of the time on customers' same? We were able to go from 10% to 50% by shrinking the delay from 2 seconds to about 600ms.
