More detail would be best. What sort of network is it? What equipment? What client and servers? What topology is in use?
In general these issues are discovered or more usually revealed using Network Management software. These cost from very little to a hell of a lot of money. They will only work if your equipment is managed, but seeing as this is an ATM forum implying it is an ATM WAN or ATM LAN issue the equipment is certainly managed.
If you have loads of traffic being created by one of the current spate of worms then you should see traffic to and from a site called Windowsupdate and on port 135. Your routers should pick this up, but even better would be to use a packet analyser, this should reveal all but you will need to be clever where you site it.

I am using a Nortel Centellion ATM Switch as my backbone with various Cisco 2950 Switches and 2600 Router.
We have discovered that most machines are issuing ARPs to unexistent machines and thus causing the congestion where you can only ping machines but not the other systems like switches, print servers and printers.
I am in dire need of a free trial system which will help me try and capture the packets.
Please help. I have patched the Windows systems with the new patch and also patching the switches with the cisco patches.
Anymore suggestions will really help me in sorting out this problem.

Try ethereal in the first instance on a machine with lots of memory and HD space. It is free and easy to install. I would look on PC Pros website http;// and look at their recent review of network analysis tools this will lead you to some free downloads after a bit of googling.
