Portable Client File Transfer Issue

[admin]

Hello,

Beware of security softwares such as antivirus / firewall which may block file transfer from time to time if considered dangerous. I do not believe there are any differences from transferring a file using terminal services and TSplus. However depending on client's operating system, you may have to update your RDP client to latest release, especially on Windows XP host where upgrading to RDP 6 or above is recommended : http://www.microsoft.com/en-US/download ... x?id=20609

Also make sure your .csv file is not used by multiple users at the same time, which may cause these writing errors.

It is not an easy issue to troubleshoot or reproduce.

We are using the Portable Client Generator to create the clients. The problem is occurring with the portable clients. We are using TSPlus 8.10.3.7. The problem does not occur with the HTML client as the file is written to \\tsclient\webfile and then it is downloaded to the browser.

The file is never in use by multiple users. It is simply created by our application and copied to the clients local drive. If it were an Antivirus problem I would expect it to happen when using Terminal Services but it does not.

So far the clients experiencing this problem are all running Windows 7 Pro on their workstations.

Hi,

I am having the same issue. There is only one file that I am having this issue with. I can copy and paste the file to my desktop and it works fine.
But Copy myfile \\tsclient\c\foldername fails. Once it fails I can no longer copy any other files. I have to end the session and log back in. I am trying to figure out what is different about this file.

Hi

I finally was able to access one of the client computers which had the copying issue. As it turns out this is NOT a TSPlus issue because the problem occurred when I used mstsc.exe with a Windows 2012 R2 server in administrative mode (i.e. TSPlus was not installed on this server). I determined that there was a change in Windows 2012 that affected the copy functions of our application. I changed the application to use Windows 2012 Copy function and it worked correctly. I then tested it on the TSPlus server with the Portable Client and it worked properly.

Hi Simon,

Can you please explain how you changed it to Windows 2012 copy?

I changed my code to generate the file on the Server. Previously in some situation the application would attempt to create file on the Client which meant that the commands being used were not standard coy commands. Once the file is created completely on the server I simply run the following Windows command:

c:>copy myfile \\tsclient\mydrive\myfolder

My development environment supports the ability to run windows commands so in my app it looks like "Run copy myfile \\tsclient\mydrive\myfolder\"

The other item that has caused trouble for some client is that the security settings on the destination folder were not sufficient to allow the file to be copied.
