I have ftp server working on windows 2003 standard edition SP2. During uploading files from ftp client program to ftp server (IIS6.0 ftp site), errors occurs sporadically. There is no pattern about error happening. It occurs by random.Files are not big. In the ftp log file, I find 426 1236 error message. What causing this error, and how to avoid this error?
When I run this ftp client program on the test ftp server it works fine, but when I try it on the production, FTP 426 errors and 1236 win32_status occur in the IIS6.0 ftp log
