Can somebody explain this? We just installed a new BladeCentre with
new HS21 blades running Windows 2003 R2. For some reason, these blades
can't get a dynamic address from our DHCP Server in Windows. However,
if I do a PXE boot, they seem to grab an IP address without any
problems.

Our existing HS20 & HS40 blades don't have any problem getting IP
addresses dynamically, via Windows or PXE boot.

All models seem to have the same network card: a Broadcom NetExtreme
II.

Here's what I get on the server console:

....and here's what I see in the DHCP Server Audit Trail:
