I have a customer who is having trouble accessing my FTP site. They
connect and log in just fine, but the LS command fails unless an LCD
command is issued first. The LCD command doesn't even need to change
the local directory. The following transcript starts out in H:\. After
  an LS fails, it issues a "LCD H:\", and then the LS succeeds. No
files are listed since the directory actually has no LIST access for the
user. The same problem is seen even with a directory that has LIST
access. Also, I see the same behavior with GET - can't GET a file
unless LCD has been called.

H:\>ftp <ftp site>

Not sure exactly what flavor of winXP they are running, but they did not
have this problem a couple of weeks ago.

How can I solve this problem, short of inserting the LCD command before
each LIST or GET?

Thanks,
Neal
