Windows XP Pro SP2 Gateway problem with a twist.... aka the 50% Problem

Posted on 2006-06-01
Last Modified: 2010-03-18
I have 6 IDENTICAL Win XP pro SP 2 machines.  Bought at the same time, made by the same builder, all identical components and software.  There was a power glitch this afternoon, now 3 of them can see the network and 3 cannot see the gateway.  All PC are on APC power strips and router, swithc and modem are on  APC UPS. Router & Modem has been power cycled, machines have been power cycled, cableing has been checked.  Netdiag shows The gateway is unreachable,  I can ping and localhost, but not the machine IP, router, or other machines on the network.  Also no internet access is available for the 3 with gatewat issues. I have used both netsh int ip reset and netsh winsock reset.  All the data on the network share is fine.

    Are all 6 workstations all connected to the same switch?  If the 3 with problems are on their own switch/hub then your issue may be there.

    or the NIC's have been fried.  Do you have a spare NIC you can install on one of the 3 machines to to test?

    It was the switch.  Powered the switch off and all came back wonderful.  I am not sure what the procedure is here for points.  [humor] Do I award myself my own points? [humor]

    But all of your answers are good, but did not solve the problem?
