    Hi Ganesh,

    I see you have DHCP disabled, so I take it you entered a fixed IP?

    One thing I noticed is that your DNS server IP's are totally different from your Gateway IP's.

    Try enabling DHCP and setting for automatic ip and dns.

    See what happens.

    If you have more than one system, it could be that the IP is already occupied.

    Post back on your findings, and give me some more details of your setup:

    How many computers connected to router, wireless or cabled, etc..

    Again, try enabling DHCP and enabling automatic ip and automatic dns resolve.
    (providing the DHCP server of the router is enabled of course)

    This will rule out double IP and wrong dns possibility so we can look further into it.

    Good luck.


    PS. The fact you state that yesterday it worked for a while and now it doesn't, could mean some other computer is already using your IP.

    Note:

    In a situation where you have so many computers on the same Lan it isn't wise to use fixed IP's except when it necessary for portforwarding or if the computer is acting as a server.

    It creates too much administration figuring out what computer has what IP and where it is located.

    Hi ganeshgun,

    Sorry, I had to go away but I'm back.

    From your last post I see that DHCP is off on the server, so you can put the fixed IP and DNS back.

    I noticed you have a Nvidia network card.

    When you installed the nvidia network driver, did you install the protection suite that comes with the driver also?

    Then you should check the settings of the suite because it is a very riggid firewall.
    It could be the culprit for not letting you connect.

    And what firewall else do you use on that computer?

    Hi,

    Put the entries back the way you had them before.

    Download this netscan tool SoftPerfect Network Scanner: fast and free network scanner

    Install on a computer that has a connection and start scanning for ip addresses.

    This wiil show you which ip's are used and which are not.

    The scanning takes a few minutes.

    By the way, can you send me the ipconfig/all from a machine that has good connection there?

    Good luck
