FTP Enterprise Stage invalid remote file Error!

[sohasaid]

i have got the error of "an invalid remote file" everytime i try to FTP a squential file from a WinXP FTP to Win2003 server..
Note: FTP server on the Win Xp is accessable and workin from the win 2003 server IE!.. so i just dun know why the datastage just cant verify it!!

my FTP Stage Inputs were as follows:

Source
URI= ftp://10.10.13.210:21/TEST/FTPtest.txt

Note: I have tried to put the computer name instead of the IP Address.. but it gave the same error
and also i added the ftp Port Number, but it didn work as well ..

Connection:
ftp commmand=ftp
Password=*******
User = soha.said@itworx.com

Transfer Protocol
Transfer Mode=FTP

"is not valid remote file" is the error which i got after alot of trials to correct this but with no use!!..

it would be great if i could get any help regardin that issue.. !

Thank you in advance..
