    Network Slowness

    Locked

    by brown.demonte ·

    Our users are having problems accessing files on file server over the network. Problem started when we updated anti-virus on this server which required at reboot. After that upgrade, anything we try to access files (word, excel, powerpoint, etc) it takes about 30secs to a minute to open documents sometimes locking up Word or other programs that we are trying to open.

    We have checked event logs but really haven’t seen any errors messages that would give us a clue to possible cause and resolution. Any suggestions on what we need to look at????

        The is not user specific. All users on the network are effected by this problem. When day try to open file from file share, it opens but it takes about a minute to open.

          could be your anti-virus software is causing the slowdown as it maybe configured to do live scans.

          We stopped the Realtime service monitor on anti-virus and that worked.

          Thanks,

          Same problem, no answer

          In reply to Re: Network Slowness

          I have had the same problem.

          To give more detail on my setup, we have a W2k serverrunning Norton AV 8.1. The first Windows XP machines came in with SP1 on them showed the network access delay of 30 seconds.

          Subsequent new machines with Windows XP SP2 pre-loaded have not shown the delay but updating the old machines to SP2 did not correct the problem.

          Does this help anyone?

          Possible answer

          Make sure that you have the AV software on both workstations and servers, and also make sure that neither have network scanning switched on. If you have network scanning on, the file is being scanned twice on opening, once by the server and then across the network by the workstation.

          That should make a difference.

          might be your anti virus software. sometime it cause problem. you can reinstall.

          have you check another workstation to see if it can access quick than another? havent you?

          i dont think it is real time. something is missing.

          NIC Duplexing

          by csmith ·

          In reply to Reply To: Network Slowness

          Check to see if you’re having duplexing problems. I usually use the poor mans test of getting a large file and try copying it with Speed/Duplex set to Auto and then after setting it manually.

      Root Certificates

      by maxsecdsl.pipex.com ·

      In reply to Network Slowness

      Stopping the real-time scan doesn’t solve the issue, merely hides it.

      If this Symantec’s Scanner (you don’t mention the AV software or O/S), then make sure the Root Certificates in Windows is up to date (Windows update, non- critical stuff).

      There was a known issue a year or more ago when one of th supplied Root Certs in Windows expired and Symantec’s software was relying on this to check validity of it’s database. The 30 seconds delay is this check timing out.

      Logoff

      by theheadmushroom ·

      In reply to Network Slowness

      We get one or two users a day for whom it takes ages to access files on the server. If they log off Windows and on again, it always fixes the problem.
      DO NOT restart the machine – if they do, the slowness remains – the key is logging out of Windows and then logging back in. I have no idea what the problem is, or why logging off fixes it, but it does. The user is then usually OK for a few weeks, until it it their turn to host the problem again!

      Try This…

      In reply to Network Slowness

      If you are using the corporate version of Norton, there is an advance setting for the file system real time protection under configuration. The default setting seems to be scan files that are Accessed or Modified which basically scans a file that you even think about, try changing this option to Modified.

      Removing the realtime protection will resolve the problem but leave your systems vulnerable.

      HTH!

        Our solution to this problem

        In reply to Try This…

        We had the same problem with our database files. It was solved by taking taking off File system realtime protection on network files (ONLY) which were already being checked by virus protection on the server. Made a 10 fold difference in speed. Norton Antivirus was checking every network file on every workstation every time it was accessed – it’s own denial of service attack!!
