Host unreachable?

Situation:
I have just purchased SmartFTP Ultimate and installed it on our Windows Server 2003 where it is supposed to run as a service soon.

But before I can do this, of course I need to set up the FTP connection and the transfer queue.

Problem:
I am unable to connect to the server for some reason, although another PC in our network does not have any problems with SmartFTP connecting to the exact same server. So my guess is that it has something to do with the DNS-Service or another service which is running on this Windows Server.

Here is the FTP Log:

NSLOOKUP root.orina.de outputs:
X:\>nslookup root.orina.de

Server:  localhost

Address:  127.0.0.1



Non-authoritative answer:

Name:    root.orina.de

Address:  87.106.115.39

Also please note that our local Windows domain name is "orina.local". "orina.de" or "root.orina.de" is a remote FTP server hosted by 1&1 which is working fine so far.

Any hints what the problem could be?

Make sure SmartFTP is not blocked by your software firewlall / antivirus product.

Thanks for the hint, I found the problem. Kinda... The default gateway was not set in the active network connection although it was listed in the IPv4 configuration of this connection. I have no idea how this happened but I reset the connection and now everything works fine.

Guess I should've checked the server's internet connection first, but you know - it's always these obvious things you check at last

All right, SmartFTP is now running as service and configured to process+monitor a specified folder and upload it as soon as the files change (which happens about every 30 minutes).

Seems to work, but only one single time. After one successful upload I have to restart the service manually to get SmartFTP to do anything again.

Any clue what's causing this behavior?

I still could not find a way to resolve this problem and I would therefore greatly appreciate your assistance on this.

FYI: I am monitoring a folder and I run a script after the upload of this folder is complete. The javascript executes an XMLHTTP request when the "OnEnd" event is triggered - e.g. at the end of the transfer. SmartFTP is running as service under a user account which I created for this purpose and I have configured the transfer queue under this user account.

Best Regards

I'm sorry but this is not something we can support.

Oh how unfortunate, why is that?

Is there any different approach to automated uploads except for scheduled tasks? Because according to the tutorial I have to restart my server (because of "Start the task when the computer starts") but I cannot do this.

SmartFTP needs to be running all the time. Make sure you don't have the On Transfer Complete action set to Close Application. It should be set to Idle.
