    Hi all

    Maybe someone can point me in the direction of some facts. Googling hasn't helped me on this one as I don't quite know what I'm looking for.

    On our corporate network, I have setup up my printer as a shared printer (on an old machine) so that me and colleague can share it. It works a treat!

    Our machines are both Windows 2000 and the machine that is sharing the printer is Windows 98. But it works.

    Our IT department are now saying that this will broadcast an awful lot of traffic on to the network and may be causing problems.

    First off, is this true? What traffic is being broadcast and where where can I get some info on it. Does the broadcasting issue on exist on XP machines sharing printers?

    Any advice you can give me with this, will, as usual, be very much appreciated.

    Kind regards

    Gareth

    You can always try just buying a Print Server.

    I would think that if it is using netbeui it would broadcast traffic but not a whole lot. Not enough to cause an entire network to slow down. They would have to setup a packet sniffer to see what is really causing the network traffic.

    It's hogwash! If you have a large network, and all the clients are running NETBEUI, you start to have traffic that consumes enough bandwidth to marginally affect things, with the emphasis on marginally. My network currently has two print servers, four computers booted, and a TiVo that's always on-line. I have a broadband router, but it's silent right now, until I do something that requires it's input. :) Here's the total amount of broadcast traffic captured with Ethereal (an excellent and free net probe) over a two minute period. If these characters can make a case that this is excessive overhead, they're in need of new careers. :D A monstrous thirty-one packets were generated, and all of the machines run NETBEUI, and the print servers are configured for Microsoft Network Printing. The TiVo stuck in a couple of those requests. :D

    I knew I could rely on the folk in this forum. Yet again, I'm impressed and grateful in the presence of your infinite wisdom!

    I think the consensus is that my little printer sharing machine isn't causing any major network problems so I'll leave it on for now.

    Many thanks guys.
