FTP error 426 with Windows IIS server

Dear SAP,

We are experiencing an issue between SAP PI 7.0 SP15 on P-Series AIX IBM Server and the Windows IIS FTP server. The interface in PI does connect to 3 systems with the FTP file adapter (a Mainframe, an AS400 and a Windows IIS FTP server). The mainframe and the AS400 connection are working fine but for the IIS we are getting a FTP failure in 90% of the transfers in 10% it works. With other clients (also one based on JFTP) everything works fine with the IIS server. The files are only 2kb and not to large as described in the File Adapter FAQ note.

There where tests with active (FTP failure 500) and passive connections, the timeout value was increased on both sides. The connection bandwidth reached never more than 40% and there were always enough CPU processes available on both sides.

Following technical details for the passive connection failure:

XI we do get following error log in MDT

2008-09-09 20:27:01 Success Connecting to FTP server "bla.com"

2008-09-09 20:27:02 Success Write to FTP server "bla.com", directory "/sapedi/Outbound/856otest", -> file "SAPASN253201157.txt"

On the IIS server side we have the following log for the failure:
