Printer / Network Error - Go slow and no images printing

[Pyroman]

Heya all,

 

MY network appears to be running quite slowly recently, it took me 4 hours to image a machine when it usually takes 2, users are finding login times are getting longer and for some mysterious reason my printers have stopped printing pictures, not all the time however usually just when there's a picture in a document, it'll print the text upto the picture then stop and kick out the error limitcheck error: image.

 

We've had no new additions to the network in terms of extra machines/switches etc that should cause extra traffic on the network.

 

Is there a program that can "see" all the network traffic and potentially pinpoint if one machine is hammering bandwidth? or any other ideas?

 

Cheers

Wireshark is probably the best software for this (free and open source) Edited May 7, 2010 by SYNACK

I prefer Agilent network analyzer has a good GUI!

sounds like you may have a faulty network card or port on a switch. If you can't identify whats going on from the software, I'd turn off switch at a time, to narrow down whereabout the issue lies. Then you will need to drill down further to the specific port/pc.

Think it might be our ancient Superstack II, just had to restart it. see if that cures the problem.
