    Actually ,  Today's Internet security suite  having inbuild firewall and in that firewall, firewall rules are preconfigured by their companies. you need set the firewall settings as per you need. may be you will find the security mode of firewall. it will ask you on which mode you want to set your firewall setting. if you will set higher security mode then it will block the sharinig also.

    please check and see if you have disabled windows firewall. Apart from that please follow the below guidelines to enable file sharing in your machine.

    Here are the step-by-step instructions to configure Kaspersky to allow file and print sharing:

    Open Kaspersky Internet Security 7.0
    Click the 'Settings' button. This opens the main settings window.
    In the menu on the left, click the black box to the left of where it says 'Protection' to expand the list of options beneath it (if it is not already expanded).
    Click 'Firewall'. This opens the firewall options.
    Under 'Filtration System', click the 'Settings...' button. This opens another settings window.
    Note: Be careful, there are two of these buttons on the same screen under different categories. Make sure to click the one towards the top.
    Click the 'Zones' tab.
    Highlight the zone for your network adapter by clicking it once. You can find the correct zone by scrolling to the right and looking under the 'Description' column. If it lists the name of an ethernet card as the descirption then that is the one.
    Note: If you have two adapters, for instance one wireless and one ethernet, you will need to do this to whichever one is used for sharing. Both adapters can be set for this as well, if needed.
    Under 'Rule decscription (click underline parameters to edit):' find where it says 'Zone Status: Internet'. The word 'Internet' is in blue letters with an underline. Click it twice so it changes to "Local Network".
    Note: Do not use the 'Trusted' setting. It is very insecure.
    Click 'OK'.
    Click 'OK' on the previous Window.
    Close Kaspersky. Do not worry, this does not close the entire program. It will still be running and guarding the PC.
    Do this to all PCs which will be used to share files and/or printers.

    Hi all

    I got solution for my question from another website
    I am including solution here

    Follow these steps to check for problems on the machine you cannot access.

    1) Open the registry editor on the machine you cannot connect to by clicking on Start, Run

    2) Type REGEDIT and press Enter

    3) Click on the plus signs (+) next to the following entries


    4) In the right-hand portion of the Registry Editor look for a key called IRPStackSize

    5) If the key exists, double-click on it and increase the decimal value to 15 and click OK. Close the Registry Editor, reboot the computer and try to connect to the network share. If you are still unable to connect follow the above steps again and increase the decimal number for IRPStackSize by 5 and try again. Continue to do this until the stack size is large enough to permit access. Personally, I had to increase the number to 25 before I could connect. The decimal range for the parameter is between 11 and 50.

    6) If the IRPStackSize key DOES NOT exist in the right-hand column of the registry editor, then click on right-click in the blank area in the right-hand column and choose New

    7) Then Click on D-Word under the Key column

    8) In the Name of the new key, type the name IRPStackSize and press Enter. Type the name with the correct capitalization as shown above.

    9) Now double-click on the IRPStackSize key and type 15 in the value data box and place a dot next to Decimal then click Ok.

    10) Close the registry editor and reboot the computer. Try to access the network share again. If the same error appears follow the steps above to increase the value and reboot again. Continue this procedure until the problem is resolved. The decimal range for the parameter is between 11 and 50.

    Have fun
    Thanks to all
