I use the Windows Scripting Host under Win2kAS to FTP send/receive files using NCFTP. I chose NCFTP because it handles communication failures gracefully and because it supports lots of command line options.

Here's a part of a .JS script file that I use to send files. Its all very basic but it might get you started if you want to use NCFTP:
Code:

function SendFileByFTP( strFName )
{
var strCMD, oShell, RetValue;

	//Build NCFTP command line
	strCMD = "\"" + strFtpAppFullPath + "\"";	//Full path to FTP prog
	strCMD += " -u " + strFtpUserName;			//Username
	strCMD += " -p " + strFtpPassword;			//Password
	strCMD += " -P " + strFtpPort;				//Remote Port
	strCMD += " -t " + intFtpTimeout;			//Timeout
	strCMD += " -V";							//No progress meter
	strCMD += " -r " + intFtpRetryCount;		//# Retries
	strCMD += " -S .tmp"						//Rename after upload hp123456.ord.tmp -> hp123456.ord
	strCMD += " -E ";							//Regular PORT connection
	//strCMD += " -F ";							//Use PASV
	//strCMD += " -DD ";						//Delete local file if successful
	if (boolFtpEnableDebug = true)				//Check if debug enabled in db
	{
		strCMD += " -d " + strFtpDebugFilename;	//Local debug filename
	}
	strCMD += " " + strFtpIP;					//RemoteHost's IP
	strCMD += " " + strFtpDropDir;				//Remote dir
	strCMD += " " + strFName;					//Filename to send

	oShell = new ActiveXObject ("WScript.shell");
	//oShell.run ("cmd /K CD C:\\temp & " + strCMD,1,true);
	
	//Execute the cmd line, window mode, pause (this) script while running
	RetValue = oShell.run (strCMD,1,true);
	return( RetValue );

}
