iis ftp: Window 2003 R2 Enterprise Edition, sp1

Binary upload reports "success" though incomplete, then stops. Report
indicates an upload speed of 100 mbits per second.

The ftp site has a 3 mbit pipe and does NOT use a firewall, the
originating site goes thru ISA 2000 and uses FTP successfully to/from
many sites.

Actual session, mput invoked with four large binary files....

Where do I go from here? There are no unusual messages in the log.

15:50:28 64.147.85.2 [1]USER xxxxxxxxxxx 331 0
15:50:35 64.147.85.2 [1]PASS - 230 0

15:53:24 64.147.85.2 [1]created /BSWA.UT987OUT.asc 426 6

Nothing in the event log

Small uploads seem to work fine.

Follow-up - bypassing OUR firewall (ISA 2K) and the problem does not
occur.

This is confusing as we ftp to/from lots of sites.

426 6 - Connection closed; transfer aborted + the handle is invalid

Obviously - ISA is causing this, though I have seen ftp itself sometimes
throw the same exception without ISA.
No clue :( try ISA group.
