I have a batch file that runs on a windows server on my dmz that will ftp files every 15 minutes to my as/400 on the inside of my firewall. Occasionally, the ftp will fail. When I check the syslog on the firewall it shows a Reset-O packet coming from my Windows server on the dmz. I don't know what is causing this. I have asked for help from Cisco because my firewall is a PIX 515 and they said that the computer on the dmz is send a RESET request and causing the connection to drop. I called the vendor that supports the windows computer on the dmz and they tell me that the RESET is the result of a dropped connection by either my firewall or the computer on the inside of my firewall. Please help.
