IIS FTP WIN 2003 - File upload restarts itself when progress gets to 100%

Hi there,

I'm having a problem with the FTP on a Windows Server 2003 machine.

While uploading large files (approx 100MB each), roughly 2 times out of three the upload will proceed fine, but on the 3rd or so file, the progress bar gets to 100%, hangs, and then restarts to the beginning again, forcing the file to be re-uploaded; this can sometimes happen several times.

Is there anything I can do to stop this? I've got a frustrated client trying to uploadfiles to my web server!

The client's uploading using Filezilla on the Mac.

Many thanks in advance,

Bluze.

Hi, Open LAN connection properties -> Advanced -> click settings button.
If windows telling you that firewall/ICS sharing service not running, would you like to run?

Click ok/yes.

After, make sure firewall is off

This should help.

OK, just gave it another go - unfortunately it did the same thing; got to 100%, and then went back to the beginning to continue the upload from the start :(

Any other ideas?

Thanks

Sounds like a tineout issue. What kind of Firewall are you running between the client and you?  Can you change the keep alive for 'any' rules to something other than defaults?  Seems that you need to increase the time out on the inbound interface.  Also could be duplex and speed settings on the interface and the NIC of the server.  See if you can change them to 100 full.

Hi there,

I can't seem to find out where to change the Duplex and speed settings - I've seen it somewhere before, but it eludes me now!

I'm running a Fortinet firewall. don't seem to be able to find any 'keep alive' settings..

Any pointers?

Many thanks..

Do you get the same problem uploading 100MB files locally? Does this server do anything else besides FTP? What is you connection speed and type to the Internet? What is your client's connection speed and type to the Internet?

The duplex and speed settings are in the NIC's configuration. (right-click nic -> Properties -> Configure -> Advanced tab) If the server is only running FTP then changing these setting would be fine for testing but if it's also serving LAN services then I would keep the NIC speed as high as possible.

Depending on the connection types involved, you may want to try the uploads at different times during the day to see if there's a pattern of better or worse performance. If there is then there's not much we can do except to upgrade the bandwidth at one or both sites.

Yes and also check at your IIS FTP server its disconnecting the sessions and when it reconnect then starts uploading from first.So check the internet Bandwidth speed specially at client-side.

Restart your complete server.

Thanks for your responses - Apologies for the delay.

Answers to your questions:

The server is mainly a web server; the ftp is being used to upload files for the web. Specifically Audio files for an MP3 downloads service.

I don't get the same problem as my client when I use the FTP service on a 4Mb ADSL connection - although my client has tried the upload on various different connections with different ISPs - he connects to the same Telephone exchange that I do.

The Speed & Duplex settings are set to 'Auto' at the moment - should I change them to 100 Full?

The client has tried at different times of the day, and seems to get the same problem no matter what.

If I could do as you suggest, Vijay, then at least the FTP server would behave as expected - at the moment, my client can't tell whether a file has uploaded or not, as it's giving these false results.

How would I check that the FTP in IIS is disconnecting correctly and then resuming from the correct point?

Many thanks,

Paul

That was it! - the FTP service on the Fortinet firewall was set to a scan status, which caused the problem; as soon as I took the protection off, uploads worked as normal.

Thanks loads gheist, and to everyone else who contributed suggestions.

FTP control connection is very tricky - firewall has to track if data is transferred and do not kill it.
