how can I find out what is using port 443?
I have a windows 2000 server that had iis and tomcat web server running on it. We don't think that either one of them is using port 443, yet when we telnet into port 443 on it, we telnet into Serv-U FTP server.
We uninstalled IIS on the server, because we didn't need it, and Serv-U still was running. I'm not sure what the process name is for Serv-U, so we can't end it or search for it.
Aside from shutting off Tomcat, how else can we verify what is launching Serv-U and whether we need it? We are worried that it might be from spyware, rootkit, virue, etc....
Does anyone have any suggestions on how we can proceed with finding out why it's there and whether we need it?

Run netstat -ano and it will tell you what ports are being used. The o option will also tell you the PID.
Then open tasks manager, select the processes tab, and from thet "view" menu, click "select columns", and add make sure the PID (Process Identifier" is checked. Now you can match the PID from netstat to the process PID in task manager to identity what process is using what ports.

Thanks...that's a good start. Any idea how I can find what or how that process is being launched?

I tried the netstat -ano, and found out that there isn't an "o' parameter available

I'm trying TCPView and Process Explorer. I'll let you know how that works out. Any other suggestions would be welcome.
It's all right here:

https 443/sctp HTTPS
https 443/tcp http protocol over TLS/SSL
https 443/udp http protocol over TLS/SSL
Is this the type of information you were looking for?

From Technet:
1076
A worker process with process id of '%1' serving application pool '%2' has requested a recycle because it reached its scheduled recycle time.
What is the source on this event ID?
OOPS, sorry:

Thanks for the info. I'm trying to find out how the ServU ftp server program is being launched. It's using port 443. We also have a problem with the web pages being displayed for a few minutes. Then shortly, while we stay on the page, it says that there's a winsock error - due to ServU....strange, because our page is using port 80.
Any ideas? Thanks for your continued help with this...

Sounds like a missing DNS entry. Intermittant coms on port 80 usually means the DNS address for that machine is missing.
But the error says there's a winsock error. So, you might try a winsock fix. I don't remember the syntax. But, there is a command that will try and fix your winsock. I think it was winsock.exe /fix.
A third idea I have is the type of switch this is on. Intermittant coms and a winsock error can be caused by a dumb switch. Have you ever heard of spanning tree port fast?
A fourth idea I have is conflicting NICS. Dual NICS on the same machine can conflict if on the same subnet. It just confuses the heck out of the 'puter.

They have a hub instead of a switch. we are replacing the switch tomorrow.
Do you know how we can find out how servu is being launched? We, and our software vendors, don't have any idea where it's coming from or where it launched from.
We need to trace where it's originating from (file location) as well as how it's launched (hjack, or reg entry, etc....)
Thanks again for the help.

ServeU has a site of their own. Have you tried contacting them? Customer service should be able to help.
http://www.serv-u.com/
If you ask me, Server U requires FTP services. It sounds like you could be FTP'ing your mail to a remote location for mail relay. Is your mail zipped up, and sent on/off site by using the FTP services?

Thanks for teh advice, but that's not answering my question. The instance we have is with ServU, but I'd like to know, in general, if there's any way that we can trace where a process was being launched...
We've scoured all of the normal startup areas and cannot find it.
Is there a tool out there that will tell us where it was launched from?

Did I understand you correctly? You already looked int he FTP logs and SMTP logs? Maybe try Event viewer. If there were an error when passing traffic it could show up in event viewer, maybe a source of that error or the text of the error will provide some insight.
If all the above bares not fruit, you may have to do a real time-port monitor or traffic monitor. Something that monitors the IP addrress. Some software you can snag a packet of information and see what that packet says. Or, it will show you what computer is talking with the server at that time.

It's still not answering my question. Please reread. I'm trying to find where a process is being launched from.
