  • Network Utilization

    What does " Network utilization " tab in task manager indicate. I have a server with around 100 clients connected using switch. Network utilization tab usually says .08%. Is it not utilising the network properly or is it a network card issue?

    Re: Network Utilization

    Where are you taking this figure from? Server or workstation?

    It measures the percentage of bandwidth being used by network adapter of the PC you are looking at with Task Manager. Copy a large file across the network and see what the % use does.
    1 1 was a racehorse.
    2 2 was 1 2.

      Re: Network Utilization

      Why are you worried? Are there network issues?
      What NIC your server has? 10? 100? 1000?
      What network are you using? Fast Ethernet or GigabitEthernet?
      What is your server doing (what services it provides to your 100 clients)?

          Yes there are. Accessing files are slow and Webbrowsing becomes intermittent
          What NIC your server has? 10? 100? 1000?
          Full duplex support at 10 Mbps, 100Mbps and 1000 Mbps operation
          What network are you using? Fast Ethernet or GigabitEthernet?
          Im not sure.
          What is your server doing (what services it provides to your 100 clients)?
          File sharing.

          This server has only one NIC port (Onboard)
          Is there any way that I can calculate NEtwork utilization? Can the slowness and intermittent issues be because of server?

            Hmmmmm...
            Still not enough info...
            What Os is the server and what OS are the stations?
            Why is the web browsing depending on this server, if it only provides file sharing?
            If it's not, and you have issues both with getting file from the server and web browsing, then biggest chance the problem is not with the server, but with your network infrastructure...
            Go to Start -> Settings -> Network Connections. In the new window, double click on the NIC. You should get something that looks like the screenshot attached. What is your connection speed?
            Another thing you should do is to check the Event log. Looks for any network related problems.

              Accessing files and browsing the web are two diiferent things. It doesn't sound like the server is multi-homed acting as your default gateway so I would suspect the problem is within your network not your server. You should download and run Wireshark or Microsoft Network Monitor 3 and run a packet capture. Look for things like a large number of broadcasts or ARP's, and look for a large number of duplicate ACK's, TCP retransmissions, TCP fast retransmissions, and TCP reset connections. These are all indications of network congestion in your switch.

                please make a drawing of you're network setup.
                It's a lot easier then sniffering if you're not experienced with it.
