For the most part this system has been working pretty reliably. However we do have periodic cases where the kiosks fail to download updates with the kiosks reporting that the connect was closed by the remote host and the FTP Logs on the server showing 426 status codes. At first I was just ignoring the errors assuming it was some kind of random network connectivity problem since typically only 1-5 of the 30 kiosks tend to encounter the problem. However, I started noticing a pattern where the error most frequently occurred while downloading one specific file (probably about 75% of the errors). The errors also do not consistently occur from any specific kiosks or physical locations. So my question is, what sort of things can cause a FTP 426 error and are there any recommendations or best practices that we can follow to reduce or eliminate their occurrences? Here is some information on our system setup: The server is a Windows 2003 Standard Edition Server running IIS 6 for both website hosting and FTP. The kiosks are Windows XP Pro all-in-one touchscreen units that connect to a Linksys Wireless Router using 802.11g with WPA Encryption. The updater application is a .net 2.0/3.0 app that uses a WCF call to download a list of updated files and then uses the System.Net.WebClient class to download the updates. iis 6.0 FTP Thanks, Shawn www.shawnsmiley.com Reply ganeshanekar 542 Posts Re: Troubleshooting FTP 426 Errors (Connection closed; transfer aborted) May 02, 2007 11:01 PM|ganeshanekar|LINK Here are few KBs from MS which talks about this but this may or may apply in your situation. 306183Repeated 426 Entries in the IIS FTP Log http://suppor

good, bad or incomplete: Range Purpose 1xx Positive Preliminary reply The requested action is being initiated; expect another reply before proceeding with a new command. (The user-process sending another command before the completion reply would be in violation of protocol; but server-FTP processes should queue any commands that arrive while a preceding command is in progress.) This type of reply can be used to indicate that the command was accepted and the user-process may now pay attention to the data connections, for implementations where simultaneous monitoring is difficult. The server-FTP process https://forums.iis.net/t/1105801.aspx?Troubleshooting+FTP+426+Errors+Connection+closed+transfer+aborted+ may send at most, one 1xx reply per command. 2xx Positive Completion reply The requested action has been successfully completed. A new request may be initiated. 3xx Positive Intermediate reply The command has been accepted, but the requested action is being held in abeyance, pending receipt of further information. The user should send another command specifying this information. This reply is used in command sequence https://en.wikipedia.org/wiki/List_of_FTP_server_return_codes groups. 4xx Transient Negative Completion reply The command was not accepted and the requested action did not take place, but the error condition is temporary and the action may be requested again. The user should return to the beginning of the command sequence, if any. It is difficult to assign a meaning to "transient", particularly when two distinct sites (Server- and User-processes) have to agree on the interpretation. Each reply in the 4xx category might have a slightly different time value, but the intent is that the user-process is encouraged to try again. A rule of thumb in determining if a reply fits into the 4xx or the 5xx (Permanent Negative) category is that replies are 4xx if the commands can be repeated without any change in command form or in properties of the User or Server (e.g., the command is spelled the same with the same arguments used; the user does not change his file access or user name; the server does not put up a new implementation.) 5xx Permanent Negative Completion reply The command was not accepted and the requested action did not take place. The User-process is di

This circumstance occurs because of a timing issue between the FTP access methods file exist lookup(fexist) routine and the Microsoft FTP server. Microsoft is currently the only known FTP server that encounters this timing issue that results in the 426 message.
