File and Print Sharing and ICS stopped working

Discussion in 'Windows Networking' started by Reggie Laffond, Sep 12, 2005.

  1. I've had a small network in my home for two years fairly trouble free. All
    boxes are Win98SE with NICs connected to a hub with CAT5E. One has a modem
    and ICS. The ICS box dials up the ISP and the others simply launch IE. All
    could share files and printers also.

    Last week my daughter said she could not get Instant Messanger to connect. I
    checked and her machine could not see two of the four. And the two she
    couldn't get to could only see each other. I tried changing workgroup names
    and computer names but the same pair can only see each other in network
    neighborhood. So now it's like I have two different networks each with two
    workstations. I know this can happen if you use different workgroup names
    but I was careful when I typed - and no uppercase or trailing spaces or
    special characters. In fact I went back to the default name "WORKGROUP".
    Same issue.

    It isn't a physical connection problem because I swapped the machines around
    to different jacks the symptom hasn't changed.

    Are ther known problems with Win98 and networking that I can investigate?

    Thanks in advance.

    Check the IP addresses and masks with winipcfg and make sure they're
    all on the same subnet.

  3. When I went home and looked in Network Neighborhood I could see the aother
    three workstastions from any anywhere. Magic. Maybe it just needed time to
    show up there. I noticed that after a reboot the other names don't always
    display but if I type the computer name in the address bar of Explorer I can
    browse the files OK (and it immediately makes the name available in network
    I double checked the subnet mask and IP addresses as suggested. Subnets and
    first two segment of the IP addresses match. But still only the ICS machine
    can get to the internet.

    Should I take this to the internet newsgroup since my connectivity issue is
    resolved or can I continue here?

    Whoa ...

    What do you mean "first two segment ..." Are you running a class
    B network? Most home users run class C (i.e. the netmask is, so that to be in the same subnet -- and able to
    communicate -- the first _three_ numbers match).

  5. Subnets match
    I can't remember what the IP addresses were (I'm not home now) but the first
    two segments match (ie.168.172.xx.xx) on all machines.

    With that netmask, the first _three_ numbers must match.
