Can the desktop pull DHCP with different wired connection?
Is is possible that NIC speed\duplex is hard coded on a auto detect
switch port? That would normally result in a duplex mismatch.
While I'm on the subject..
It is a common mistake to hard code speed\duplex without making sure the
switch port is also hard coded. Auto negotiation relies on FLP's (fast
link pulse) sent by NIC and switch port. Hard coding one side breaks
this. For reference cisco.com has a nice table on valid settings.
