    Just bcos you have a Cisco switch doesn't mean it can't break. The good
    switches but they're not indestructible. Also look at the cables themselves
    are the bough or made? I had a very
    similar problem a few years ago and it turned out to be the switch I was
    using. Never rule out anything based on a product name, they all break,
    eventually.

    Hi All,

    Well let me add something more, this has started happening since a couple of
    days,do any of you think it could be bcos Eth1 which is the Internal
    Interface is getting clogged with the number of requests that are coming
    from the Windows Clients?and morever bcos of the Blaster Virus and
    Vulnerablities on Ports 135:139, the network may be getting jammed and hance
    not accepting the ping requests!Therefore is it wise to increase the Buffer
    Limits of TCP requests ?If yes can I know how it can be done?

    I have also attached the Firewall script that I am using.

    And Yah cant be a Rj 45/switch issue bcos I am using a Cisco Catalyst 2900
    switch, which is fairly a great switch to have.

    Your thoughts on this will be helpful.
