WINCE 6 Device Not reachable by Server, But Can via Laptop RRS feed

  • Question

  • Hi All,

    Im in need of some help as I don't know where/what to do.

    I have a Server running SQL Server 2005
    I have a Laptop running Windows 7 64bit
    And
    I have a Motorola MC9190 running Windows CE 6.0

    The server and laptop are both on a domain.

    The server is on a wired Network
    The laptop & handheld device are on a wireless network.

    Now,

    From the Laptop I can ping Both the server and the handheld device
    From the Server I can ONLY ping the laptop and NOT the handheld Device
    From the Handheld I can ONLY ping the laptop and NOT the Server

    I cant figure out why this is.

    Laptop Settings:
    IP Address: 10.81.203.64
    Subnet: 255.255.0.0
    Default Gateway: 10.81.12.10
    DHCP: 10.80.52.31
    DNS(1): 10.80.52.31
    DNS(2): 10.10.52.31
    WINS(1): 10.80.52.31
    WINS(2): 10.10.52.31

    Handheld Settings:
    IP Address: 10.81.203.67
    Subnet: 255.255.0.0
    Default Gateway: 10.81.12.10
    DHCP: 10.80.52.31
    DNS(1): 10.80.52.31
    DNS(2): 10.10.52.31
    WINS(1): 10.80.52.31
    WINS(2): 10.10.52.31

    Server Settings:
    IP Address: 10.80.203.94
    Subnet: 255.255.0.0
    Default Gateway: 10.81.12.10
    DHCP: 10.80.52.31
    DNS(1): 10.80.52.31
    DNS(2): 10.80.52.32
    WINS(1): 10.80.52.31
    WINS(2): 10.10.52.31

    Can anyone help me out with anything.
    Thanks in advance

  • Your server settings seem to be wrong.

    The default gateway is not on the same subnet as your server. Change the server IP address.

    Server Settings:

    IP Address: 10.81.203.94    <=== Maybe this is what you meant?
    Subnet: 255.255.0.0
    Default Gateway: 10.81.12.10

  • Hi Mario,

    Thanks for your reply.
    For the IP Address

    .80 defines its a wired network
    .81 defines its a wireless network

    and just to double check I did change it, resulting in an offline server.

    Thanks
    Alex

  • I think Mario is on the right track. Apply the subnet masks to each of the addresses assigned to each device and see what you find:

    Server Settings:
    IP Address: 10.80.203.94
    Subnet: 255.255.0.0
    Default Gateway: 10.81.12.10
    DHCP: 10.80.52.31
    DNS(1): 10.80.52.31
    DNS(2): 10.80.52.32
    WINS(1): 10.80.52.31
    WINS(2): 10.10.52.31

    Applying 255.255.0.0 to the server IP makes our current subnet 10.80.0.0 (it's a simple mask). However, 255.255.0.0 & 10.81.12.10 for the gateway yields 10.81.0.0. The gateway and the device itself are on different subnets. When you try to communicate with an IP on another subnet, the server should try to send that request via the default gateway, but given the gateway address, I don't see how that could work.

    How are the subnets 10.80.0.0 and 10.81.0.0 separated from one another? What sort of router is 10.81.12.10? It's configured correctly to have separate IP addresses on the two network segments it serves? Maybe you just need to configure it to have a 10.80.x.y address as well as the 10.81.12.10.
