I spent about 90 minutes with Ben (GrnTaco) on the phone today while logged into his machine remotely... We got him pretty well figured out, but there's still an issue with (we're thinking) the Dell remote support application on his laptop holding port 80 open.

But... (and SolidDigital, this is why I bring this up) we got around it for the time being by setting up a redirection for port 80 traffic to an unused IP address on his network. You might want to do the same until you can figure out who's got remote spooling open.

Down that path though, there are a couple of things that you can check on the side:
  • I would first work to figure out which computer has the port open. You can do this by pulling one computer at a time off of the network, then running the Shield'sUp test on the other one. If I had to guess, I think you'll find that it's the Windows 98 machine.
  • I know you want to be able to do this, but turn OFF "Share my printers" in the network control panel. That should kill the remote spooler.
  • Turn OFF NetBIOS support. Doing this will cause issues with being able to "browse" your local network, but it'll be safer overall.
  • Create a static route in the router and point 515 traffic to an unused IP address.
Lemme know what you find out.

Oh, for the record, getting Win98 and XP to happily share devices is "fun" and "exciting". You'll want to be sure that the Win 98 box is SE, and that you have SP 2 on the XP box. Any chance that the 98 box is big enough to handle an upgrade to XP?

Greetings,
Since the webserver is a service, you can simply set the service to only start manually. It won 't make a difference if there is software running that wants to open the webserver. Redirecting the port to an unused IP address can cause trouble by utilizing resources on the PC.
IMHO, you must set the Service to Manual and remove any software that is calling for an open PORT 80 Service.

Right... This was a temporary fix until Ben/we/someone can find the app that has the port open. It didn't jump out at me when I was wandering the box.

Right... and that will happen as soon as Ben/we/someone finds the app that is holding the port open.

the weird thing is I can't access network options on the windows 98 computer.. but I did turn off 'share my printers' on this one and 515 still shows up open.
Guess I'm pretty stupid when it comes to networking stuff, I can't even find anything that says netbios to turn off lol

only thing I've found on my router page is "virtual servers" where it has "description", "inbound port" which has a box, dash and another box, "type", "private ip address" and "private port"

the computer downstairs is only a 300mhz P2 with 64mb of ram and 4mb video card. kinda think xp would kill it haha

I checked it the other night when the old computer was shut down, and 515 wasn't open. Now today the other computer's on and 515 is open again.
