LAN Tool to detect traffic and broadcasts sent? 1

[SteadySystems]

I've posted a few times regarding winxp/win2k tools and cleaning up a LAN.

We share a T1 line with another company.

The problem: something on our network is dragging down the T1 connection. It is coming from our side because when we are unplugged from the patch panel the T1 speed for the other company is 100% fast.

when its normal: I do a ping google.com -t and our ms is
63ms

then all of a sudden there is a spike that last for minutes upon minutes and I do a ping google.com -t and the ms is 1028! or higher.

So I have since ordered DSL 700 so that the other company is not effected and we have our own line. Also have ordered new computers to replace the olders ones and bought a new hub. Ordered new CAT5 cables for the patch panel/hub. 3ft - 5ft. Our router will remain the same, linksys.

What I need now is a lan tool that detects all the computers on the network and see if there are any spikes and where they are coming from.

Does this exist?

Thanks in advance.

For your manual DNS entries, make the first entry to the DNS proxy on the router: (assuming its IP is 192.168.1.1)

If your T1 is slow, do a download speed test (Google it). Do a few. Sounds like you have a trojan on a machine uploading info to an attacker. Get a cisco adsl 837 router. You can use it as a dsl modem, firewall (very good one), to log and stop attacks with acl's, and it can be used as a packet sniffer as well. I got mine on Ebay with the latest IOS for under $200.00.
