    Hi,

    I have a local network in my office. I can ping the PC in my office but cannot access it. Everyone else in the office can access it. No one can access my PC either. I have Comodo Firewall installed. I have already tried to change settings on my firewall but nothing is working, not even shutting it down completely. The PC is on the local network. Help!

    Is your PC in the same workgroup as all the others?

    Some software firewalls have an effect even when disabled - you need to try completely uninstalling it and see if that make a difference.

    Also disable Windows Firewall.

    Turn off any firewalls for debugging. If the firewall is the problem, you'll have to configure it to allow access to "trusted zone" addresses. Note that some firewalls must be completely uninstalled to stop them from affecting your networking.

    Hold the Windows key and press R, then type CMD to open a command prompt.

    In the command prompt window that opens, type type the following commands:

    PING each remote computer by IP address, and if successful, PING by name. Open a command prompt as described above and type.

    PING <ip address>
    or
    PING <computer name>


    Where:
    <ip address> - is the x.x.x.x IP address
    <computer name> - is the computer name

    A failure to PING is almost always a firewall configuration issue. Any failure to PING needs to be corrected before you go any farther.

    Note: You can obtain the IP address and computer name of a computer by opening a command prompt (DOS window) and typing IPCONFIG /ALL. This should work for any Windows version. The IPCONFIG /ALL display will provide a wealth of useful information for debugging your network connection.

    Check your Services are Started on all PCs:
    • COM+ Event System (for WZC issues)
    • Computer Browser
    • DHCP Client
    • DNS Client
    • Network Connections
    • Network Location Awareness
    • Remote Procedure Call (RPC)
    • Server
    • TCP/IP Netbios helper
    • Windows Zero Configuration (wireless configurations)
    • Workstation

    Note: You can check the services in Control Panel, Administrative Tools, Services.

    All of these services should be started, and their startup type should be automatic.

    All computers should be in the same workgroup for computer browsing to function properly. File & Print Sharing has to be enabled on any computer you wish to share files or printers from. You also need to actually share the resource in question from My Computer, right click on the drive/printer/folder, and select sharing.

    If you encounter difficulties accessing computers that are visible in Network Neighborhood, make sure the computer being accessed has an account with the same name/password as the system connecting to it uses to login.

    While the default NetBIOS setting is correct for normal network configurations, it's possible for it to be altered, and it costs nothing to make sure it's correct. NETBIOS over TCP/IP must be enabled for normal network browsing.
