  • Slowness in computers when working in Domain

    Hello,

    We are working with a 2003 domain.
    it seems that when computers connected to the Domain (They all members in the Domain), they work slow. sometimes very slow.

    all DNS are configured ok.
    We use the latest version of Trend Micro security client for all Domain computers connected to a Trend Micro server.

    Any idea what can cause this ?

    Thanks

    What precisely is "slow":
    Application performance? -- check processor or RAM (or flux capacitor)
    Accessing files over network? -- check LAN (or flux capacitor)
    Internet access? -- check router (or flux capacitor)
    Typing? -- change keyboard

    Give us a lot more information to have a chance of answering meaningfully

      It looks as if everything in the computer works slower.
      I see the HDD working much harder.

        Are these clients (what OS) or servers?
        Desktops or laptops?

          trend micro could be scanning all files on any access.

            So do they work faster if NOT connected to the domain (but still domain members) e.g. roaming laptop users?

              Hi,
              yes these are computers not servers.

              And they work faster if they are members of a domain but not connected to a domain

                Might want to check the settings of your AV and make sure they are not scanning unnecessarily.

                This happens a lot.

                  Our enterprise recently had issues with network slowness (particularly during logon) after upgrading our workstations to OfficeScan 10. I believe that it was related to the new behavior monitoring feature.

                  I'm not the "virus guy", but I believe that the behavior monitoring feature is configurable though the OfficeScan console. I recommend you try disabling it on a few test devices and see what effect that has.

                    Do you map any network drives when you login to your domain? If so, this could lend credence to the AV notion. Your AV may be scanning the mapped network drive(s) once you login.

                      Another thing you may want to check is where the client is authenticating. In other words, do you have multiple domain controllers (in remote sites)?

                      If your Sites & Services are not properly set up you many be authenticating against a remote domain controller, which could also add latency.

                      On a client having an issue, type SET at a command prompt. It will spit out a lot of information. What you want to look for is LOGONSERVER. Make sure this value is your local domain controller.

                        A) When you have the computer logged on without the cable, Plug Cable in, Is computer still slow?
                        B) Log computer on with cable, remove cable. Does the slowness go away the second you remove the cable, or does it remain slow?

                        I just wrote up a massivly long table in text that explaned what these ment, but it was converluted, and ugly. So, these 2 test should let you pin point where the problem lies (At Boot, At Logon, At computer boot, or at windows start up).

                        If you get a brand new computer, add it to the domain WITHOUT any of your automated deployment (client apps and ect) does it get slowed?

                        If you have Laptops, are they effected on both the wireless and wired networks?

                        Also, get a hardware monitoring app, montior the hardware with cable unplugged and cable plugged.

                        Unplug everything from your network except for your server and a single work station (or isolate with different network hardward).

                        Once the above is completed we should have a fairly good idea of where the problem lies, rather then hepas of people asking the odd question.

                        Disable Trend and try (I hope to god that you have tried this and just forgot to mention it)

                        Wofen.

                        PS : It always helps to provide as much infomation as possible when requesting help. So far we have spent 12 posts and over 2 weeks just trying to get the infomation from you needed to resolve the problem.
