The identified problem was account mismatch between by which winscp was running and IIS pool identity account. Winscp was not picking up the pool account (Network Service) rather running with Local System account. After changing the pool identity account to Local System, it worked fine.

Thanks for sharing this.

There's FAQ covering these kind of issues:

I have identified the IIS (6.0) process w3wp.exe is failing to write/create file in the temporary folder on the windows server. As I ran from my development machine there was no issue. The NETWORK SERVICE user has the right permission for the process. I don't know what else need to be done.

Sorry, I have no experience with IIS and this is really out of scope of this forum. Try asking on sftp://superuser.com. If you do, please share link to your question here.

Hi prikryl,
I have identified the IIS (6.0) process w3wp.exe is failing to write/create file in the temporary folder on the windows server. As I ran from my development machine there was no issue. The NETWORK SERVICE user has the right permission for the process. I don't know what else need to be done.

Please suggest me in this regard.

Thanks,
Mostafa

Ok, does your process have a write access to C:\WINDOWS\TEMP\ ?
Can you attach a complete debug log path (set Session.DebugLogPath) using WinSCP 5.2.1 beta?

How to provide write access to the process for the folder in Windows?
