Hi

I have set a 'landing pad' in the appeonfileserver.xml per this post -> https://bit.ly/2VH8Y8W

The path is set to a C:\temp\ on the very same server.

When my web app is run on the server's browser, the file server downloads a file from a different drive (d:\) on the same server to the land pad. However, the downloaded file has zero bit. 

I have checked the security and permission on both locations. They both have the Fill control granted to IIS_IUSRS

The original file on D:\ is a legit, wholesome file.

I also found out that when I run the web app from another remote server, on the FIRST IWA run, the function downloaded an empty file as well. BUT, when I ran the app via the IWA icon the second time, the file downloaded just fine. 

A few minutes later (I'd say 30+ minutes without any further operation), the zero-byte file download happened again. It is though there is a window when fileserver's download function works... It's a bit spotty. 

What could possible go wrong?

Any insights?

Thanks
