Networks

We use ISDN and the connection stays ON!!

oh dear, i suggest you withdraw this question and repost it without your ip addresses. we don't need them to help you and it is not recommended practice to publish ip, name or address information to the public. those blessed bored 13 year old whipper-snappers, you see...
i wonder if you need to set up a real DNS server on your network. anything it doesn't find on your network it can send out to the internet DNS server...i wonder if you have kazaa traffic or something. are you using the NAT in the router to close all the ports except 80 and whatever you need for mail, pcanywhere, streaming, messenging? those get routed to appropriate server? you need a packet sniffer, you need somebody who knows how to use a packet sniffer...why don't you give your ISDN provider a call and explain what is happening and see if they have suggestions... answer) but doesn't it sound just like a DOS (denial of service) hack-attack? do you have a firewall between the public server(s) and your network? between the public servers and the internet? on the workstations? did this used to work without this problem? what have you tried? PS hope you turned back on automatic windows updating...

of course you are inspecting everybody for viruii...and using ad-aware to get rid of spyware...and looking for kazaa and other file-sharing programs...have you inspected and patched against the blaster worm? that would pour traffic out onto the Internet...

Shut down all of the pc's and boot them one at a time till you find the pc or pc's that are flooding the network.

It sounds like you have a worm, virus, or as another has suggested Kazza.

Update virus, verify patches, download and run spybot.

Good Luck

Sounds like you are gonna need it.

Your ip addresses (192.168,x.x)are private and not usable or routable any place except on your LAN.

ISDN? Most ISDN connections are about 128 k (about twice as fast as a dial up).

Having 32 workstations trying to hit the internet with that small a pipe will lead to nothing but frustration.

If you are going to use ISDN and get even minimal
peformance ,you should set up a caching proxy of some sorts.

As for your traffic issues,are all of those boxes patched and up to date with the latest M$ patches and virus protection?
Try turning on only the Win98 machines and see if the problem goes away.If it does, you got Blaster.

You should call up your Intermediate Unit and see if they can refer you to a contractor or consultant that can troubleshoot these issues.

I do this for the county school districts here in Pa. through their IU's. It an easy way to get specialized tech support from your school district with out them complaining too loudly.

We are a bit more pricey then your in-house techs,but you get what you pay for.
