FTP no longer works correctly RRS feed

  • Question

  • Within the last 5 months  something has changed  where the FTP Server  running on my 2008 R2 Standard no longer works correctly..    At first I thought it was because  I upgraded the clients to IE10 ...  I can connect to FTP SERVER and can switch WINDOWS EXPLORER View   BUT   It does not open the files correctly in View,  I can copy   and paste into the folder though...  

    I then tried Firefox, Safari, Chrome   these browsers  used to work  BUT they NO LONGER work...  So I have concluded that  some update from Microsoft  changed  some settings on my server between Jan 1/2013   and   5/30/2013..    Because  Jan 1/2013  was last time  I used my FTP server...  I have seen on web where people are experiencing problems with FTP   and help would be great!

    Thanks

    Take a look at other related threads this poster found.  There is more specificity in them.

    There are workarounds but they are not being accepted by the complainers.   ; }

    I'd also think about using ProcMon

    That shows that there is no problem with the connectivity.  It's what happens to the file after it is written that is the puzzle.  I still haven't figured out how the size is changing but I think that understanding that would definitely help in a diagnosis or more accepted workarounds.

    Thanks... I'd only seen this question and was trying to assist with the resolution.  Didn't think to check other posts they'd posted on to see if there were related issues that way.  Still a newbie at helping on the forums. : )

    In my opinion, the next thing I'd do is put the FTP Server into a higher verbosity for logging and try to compare the good connections vs the bad connections from the FTP Servers perspective.  I'd also check the AntiVirus on the Server to see if for whatever reason it was doing something to certain connections (maybe based on headers?) and try briefly disabling it to see if that allows the other browser connections through.

  • Firstly, you might get better response by posting this to the Server forum: http://social.technet.microsoft.com/Forums/en-US/winservergen/threads

    Second, taking the browsers out of the picture, have you tried connecting from the command line FTP program to your FTP server?  This may give you more information than you are currently getting from the browser's, which perform the action behind the scenes.

  • I can connect with command line FTP program,,  Also filezilla  works fine,,,   I can connect to FTP SERVER and can switch WINDOWS EXPLORER View  with IE10   BUT It does not open the files correctly in View,  I can copy   and paste into the folder though...  

    The other browers give me a prompt for user name and password  but that is  All.....   I never made changes to the server  except for allowing  Microsoft updates  which all installed  successfully... 

    All browers  used to work   and   WINDOWS EXPLORER VIEW   used to display  TXT, JPED, PDFs  correctly within explorer...

  • Without specific details and it working on one platform but not another, I'd look to the FTP logs between a good connection and a bad connection and see if I can see a difference.  I'd also think about using ProcMon to try and watch the connection and attempts from the FTP Server side to see if something is erroring on a bad connection that isn't on one of the methods that works.
