Thanks for the suggestions: OS is XP
MAC address for machine matches what is on the switch. Tried turning off wireless interface -- no difference IP Address is assigned by DHCP reservation. It already is on same VLAN as all targets, and same VLAN as all machines that cannot ping it. I did not try a static IP. I have however confirmed that if I map a drive to a server share the server sees that the connection is from the correct address -- but cannot ping it, nor can any remote management be done from the server. RPC & other services are all in the same state as an identical machine that I *can* remotely manage & *can* ping. Network Card settings are also in same state. There was one additional network component on the bad machine "Oddyssey network agent". No change whether it is enabled/disabled. I won't be able to do anything further until next Monday. Maybe it will go away by itself over the weekend.
