testing a network

[AHarvey]

Hi all,

We use a chat program in our work and we experience serious lag with it, but not all at the same time. We may get the odd period of time that we do all suffer a major lag session but usually it varies for each employee.

However, we have people that use the same program from home and our office in London however none of them experience this lag.

It makes me think that its either a bottleneck in our network setup or our broadband throttling our traffic.

Our tech team consists of a 20 year old lad with zero knowledge, he has only just learnt to create roaming user profiles and they don't work So my supervisor has asked me to look at it.

Does anyone know of any software that will analysis the ports on my system so I can see what port this program uses?

I also need some software that I can use to analyise out network to see if there is anywhere that we are getting a bottleneck. Does any software like this exist?

Any help will be gratefully received!

There are lots of freeware tools that show you what ports are open and communicating, easy built in way is to run the app then do "netstat" in Command prompt. For more detail look at something like wireshark.
Wireshark would be good to run when you get the lag and when you don't to compare traffic at the NIC. Should highlight stuff like heavy broadcast traffic etc.
