Is the service running under a windows account that has privileges to read/write files in the shared directory?
I had created the directory in the shared drive through Filezilla and gave read, write and execute permissions to everyone including user and other members in the group and all . Also I have been able to create a file in that shared folder by loggng in to the windows machine using the same username and id
Please let me know if there a fool proof test to know if the user id doesn't have permissions to create a file there
I don't think you need to double-up the backslashes in the directory path. Try it with just \\st-con-02\fm2appsdev\IDS1\IOR1.
You can check the Application Event Logs for a more specific error message, it that doesn't take care of the problem.
