I completely forgot about this. Now that it was brought to my attention, I’m going to try one more time; hoping I can get it to work. I’ll post a follow up regardless the outcome.

Hey, Christopher.

Were you finally able to get this working for you?
I have spent the last 2 days trying to solve the same issue but FtpUse does not work for me on Windows Server 2012 R2. I went as far as changing the Dokan version and trying many other things. In debug mode I get error 1450 referring to storage driver problems.

FtpUse works partially, notepad++ is able to writ tot the mapped drive (remote ftp server) but MS office applications fail for some strange reason..

I can successfully login to the account which I tried to login with FTPUSE on Windows10; but on Windows10 I get the error posted in my last reply.

This is the first time you actually wrote the syntax correctly here. You know, computers aren’t people, they need it exactly to the letter. I can’t obviously check if the details you provided were correct or if there wasn’t something blocking it at your site. Try connecting with a different FTP program to check that the details you have work at that particular computer, then use them exactly in the command line.
I checked it on Windows Server 2003; if you have a different version of Windows, that might be it.
