FIX: A file is not removed from an FTP location when you use BizTalk Server 2006 R2 or BizTalk Server 2009

Article ID: 976891 - View products that this article applies to.

SYMPTOMS

Consider the following scenario in Microsoft BizTalk Server 2006 R2 or BizTalk Server 2009:

You retrieve a file from a subfolder at an FTP location by using an FTP receive location.
While BizTalk Server 2006 R2 is processing this file, the FTP connection times out.
After some time, BizTalk Server 2006 R2 opens a new FTP session, and then issues a DELE command.

In this scenario, BizTalk Server 2006 R2 cannot delete the received file from the subfolder at the FTP location. Additionally, the new FTP session is closed, and you can see log entries in the BizTalk Server 2006 R2 FTP log that resemble the following:

< 220 Microsoft FTP Service
> USER anonymous
< 331 Anonymous access allowed, send identity (e-mail name) as password.
> PASS xxxx
< 230 Anonymous user logged in.
> PWD
< 257 "/" is current directory.
> DELE file_name
< 550 file_name: The system cannot find the file specified.
> QUIT
< 221

When the BizTalk Server 2006 R2 or BizTalk Server 2009 next polls the FTP location, BizTalk Server 2006 R2 or BizTalk Server 2009 opens the FTP location and downloads the same file again.

CAUSE

This problem occurs because BizTalk Server 2006 R2 or BizTalk Server 2009 does not issue a CWD command before it issues the DELE command. Therefore, instead of trying to delete the file from the configured subfolder, BizTalk Server 2006 R2 or BizTalk Server 2009 tries to delete the file from the FTP root directory.
