command line ftp hangs in Windows 2003 server

Hello,

I've a problem with the command-line ftp in Windows 2003 Server. Unitl this
morning command-line ftp worked fine. But this morning I ran a few windows
security updates and after that the ftp command gives problems. I can make an
ftp connection to a remote host (hosting provider) and I can logon and set it
to passive mode. But I can't get a directory listing or copy files. It starts
the command and then ftp seems to hang forever.

Can anybody help me fix this problem?
