duemilanove + ethernet shield

hi,

a few weeks ago i could send emails with my board. but since last week it does not work anymore, i get a new shield and tested it with the simple webclient example, but it doesn't work, i think the ethernet initializing doesn't work because i could not ping the board.

the leds flash right on the shield and i use the mac address from the shield.

i don't no whats the problem, is there a defect with the duemilanove (i can control sensors), can somebody help me?

did you or your internet provider change some settings on the network?

no, nothing has changed.

my board is not listed in the "arp -a" command.
