iis ftp: I'm having problems with the Microsoft FTP client "hanging" when run =
from a batch ftp script. I've recorded the log messages from the FTP =
session below (names have been changed to protect the innocent). The =
activity I receive in the client session is the message about opening =
the binary mode connection. The session is hung at that point and =
persists until manually terminated. I did run a netstat on the machine =
where the session ran which showed the connection in the CLOSE_WAIT =
state. This client was contacting a Win2000 IIS server at one of our =
vendor's sites. We've also seen hung sessions when contacting our own =
Win2000 IIS/FTP server using the MSFT FTP client from both WinXP Pro / =
SP2 and Win2000 Server.

Can anyone suggest what might be causing these hung sessions and what we =
might do to force the connection to close? We tried putting a timeout =
parameter on the scheduled task job that the script runs from, but the =
hung connection doesn't seem to be recognized and the task doesn't flush =
when it exceeds the runtime limit. Am I misunderstanding the =
function/purpose of the "Stop the task if it runs for 0 hours 2 minutes" =
in the settings tab of the Task Scheduler which spawns the .bat job =
which runs the ftp job.

We see this problem with hung sessions 2-3 times a week from a scheduled =
task that runs at 5 minute intervals, 24x7.

Thanks in advance for any help. Please post any responses to the news =
group.
