problem with installer 6a2 and python 2.3 ftplib

[ardechou]

hi , 
i have to build an application whoi using python 2.3 
This application is running on python 2.2 , but i want to change to
python 2.3.
So , i used in my application ftplib to search a file in unix server.
it's simple , i used 
t=ftplib.FTP()
t.connect("server_unix)
t.login("login","pass")
list=[]
t.cwd("/home/source/")
t.retrlines('LIST',liste.append())
t.quit()

so , no problem when i used the source directly with python2.3
but i want to have a standalone version , so i try to use installer
6a2
and the command t.connect("server_unix") does an exception
i don't know why , the source version is ok with python.exe and the
standalone version with installer 6a2 does'nt work ....

Thanks for your help
