TCP/IP troubleshooting

I've had ethernet and other tasks running well on my MCF52231 'Digibutler' board for some months and suddenly there is no ethernet access. The startup looks good reporting 'Ethernet started, Iface: 0, IP:' and a led shows on the router, though the router doesn't recognize the board.  There is no response at all when I try to access the board with IE.  I've tried different cables, direct connection with X-over, reflashing etc.  Is there something I can do in debug, say to find if the chip is at fault?  What signals could I measure with a scope?  Any help would be appreciated.
