Call your cable/internet provider. Some cable modems/providers limit the number 
of DHCP/mac addresses allowed per connection, here in our area the limit is 3, 
after than you have to pay for more. Have run into issues before, just call 
company and explain that MAC "xx:xx:xx..." is your new NIC and you can't get a 
dhcp lease with it, then ask if there is something they have blocking it?

That would be my first thing to try, second would be to utilize a different 
network (cheap $20 dsl/cable router oughta work - try it isolated and see if it 
gets a dhcp lease) - that way you rule out the issue being the network vs the 
machine vs the software.
