    Network on the go slow again...

    I'm struggling with this still.

    Following on from my rant in Behind the Red door my network seems to be running very slow.

    I get these blips every so often and have no clue what it is!

    I've tried Wireshark but i have no idea what any of it mean or if im using it right, so any help would be great appreaciated.

    Getting like 50/75% packet loss when i ping the DC from a client. Happens with my other server and the admin server too.

    Any ideas?

    Your not running a network asset scan (SpiceWorks), downloading Windows updates, AV updates, or the likes that will be hulking the bandwidth? SpiceWorks used to kill the network if done at the right time of day!

    do you have managed switches to check if you have not got a network loop?

    have a look at solarwinds orion to test network performance ( free 60 day trial)

    Do you get the same behaviour to clients on different switches? maybe its a switch issue

    any logging/management available on it?

    The switches keep popping into my mind..

    These are LA switches so i dont really have a lot to do with them. Am i right in thinking they can be managed remotely by Link2ICT? Sorry, i'm still a novice when it comes to switches.

    Do you have any internet routers in the school, like the ones you get for home broadband? The other year we had one plugged in to allow for unrestricted internet (don't ask). We had a power failure and all servers went off (safely) but upon reboot the router came on first and began dishing out DHCP addresses to the network, because it can back before the Windows servers.

    Gave similar issues to above (although we could not log in at all).

    Are these blips always during the day at certain times?, what you can do is run the mutiny software from Mutiny - Welcome, This is free for education users and gathers the snmp information from switches and servers. i have seen a demo and it looks good and i hope to get it running on my network, as normal the advanced stuff will cost extra but it should give you a few clues.

    Happy hunting

    Might be worth asking them? Sorry I've no idea how they deal with management.

    Might be worth giving them a sneaky reboot as a first port of call?

    I would send them on a reboot (the switches) and see what happens, in this situation it could just be a reset thats needed.

    What make / model switches are they ?

    They are HP procurve something or other lol

    From what i can see so far (unless its teasing me!). Rebooting the master cab seems to have solved the issue, everything seems to be chugging away happily. *fingers crossed so tight they are turning blue*.

    Would this have been a bottle neck of some sort then if this is the case? Is there something i've done that i can avoid next time?

    Thanks guys

    No Probs, glad thats worked for you. It may have been a bottle neck, sometimes though if switches have been on for a long time they just need a quick boot up the backside lol.

    Also, if you do have things that update like Windows or AV Scanners etc etc try and set them up to do it at different times of day or on different days to others this may have been your problem.

    Hope everything is tip-top now.

    .
    Unless you use cisco in which case they sit there happily forever (or until the hardware physically fails completely)

    We use procurve switches here and from time to time (maybe once every 6-12 months) one will randomly go loopy, quick reboot normally solves the issue. It's worth making sure you keep the firmwares updated too.

    yeah you cant beat Cisco switches for reliability but we run a completely Nortel network here and one of our switches currently has a 12+ month uptime so again some good switches we use 450-t and 5510's.

    As for pro-curves I've not had that much experience with them.
