Looks like you might have two requirements:
#1) Access a Windows share using alternate credentials.
Serv-U supports this by combining settings on the Virtual Paths and Directory Access tabs in the right way. First, you need to have your share defined as a Virtual Path, such as "\\server\share\folder" mapped to "%HOME%/sharefolder". Then, you need to have Directory Access set on the physical path (e.g., "\\server\share\folder"). Now, to get the alternate credentials, click the "Advanced >>" button on the "Directory Access Rule" dialog, and you'll see this:
#2) Scheduled sends of files from one FTP server to another.
To do this, download our free FTP client, (FTP Voyager), and use the FTP Voyager Scheduler utility to schedule transfers to remote servers via SFTP, FTPS or plain old FTP.
If this is a good answer, please mark it "correct" or "like" it.
