Hi Team,

I have been using CompleteFTP for my server for around 2 years.
Early this month my server was restarted due to urgent maintenance.
Later we found that the 'Complete FTP Service' service is running (able to see from windows services mgmt), but from the Complete FTP Manager it is not (as img attaced)
[ img ]

I went to click on the start button and recieved the error message of "Error: Site fialed to start any listeners".
So I went to logs and found following trails:

I have already checked if any other programs using port 22 (via tcpview.exe) or any firewall blocked (via telnet port 22) locally on the server, but so far I have found none.
Kindly advise on the situation... :cry:

It certainly looks like something else is using ports 21 and 22.

Could you run netstat -a on the command line and send us the output? And send us your config.sdf file?

Sorry for the wait, I managed to get the results as requested:
Follows are the output from netstat -a:

Please don't make you config file publicly available as it contains sensitive information!
I've removed the link from your post.

These lines:
TCP sinccbap2k3p19:ftp sinccbap2k3p19.sq.com.sg:0 LISTENING 
TCP sinccbap2k3p19:ssh sinccbap2k3p19.sq.com.sg:0 LISTENING

indicate there's something using the FTP port.

I suggest downloading Microsoft's TcpView to find out what it is.

Hi,
Thank you for your support. We have find out the port actually holding by 'zombie' process due to last reset.
But why I am still able to telnet that port?

P/S: is the nick support2 also from your team?

I presume that the reason why you can telnet to the port is that the process is actually still running. What's the name of the process?

Yes, support2 is one of our team. He's camping at the moment. Last time I heard from him he was on top of a mountain, which is the nearest place he could get mobile reception.

The zomebie process seems to be an instance of Complete FTP Service.
We have no ideas why it happened.
Perhaps by them time of restarting the machine, there was actually an active connection being opened....
We will keep monitor and share if we manage to find out the real culprit.
Again, thanks for your support. :)

So, is it working now?

Yes, back to business.
I stopped the sevice, and closed the application. Then, killed the zombie process.
Finally tried to start the server agian.
