HyperV 2012R2 boot to iSCSI via iPXE

About the DHCP issue: I think you're using port spanning (or whatever it's called) which makes the switch ports init slowly, which means dhcp times out, because the link-up takes too long. Try enabling something called portfast (or something). That's supposed to work.

You need to type "sanhook" instead of "sanboot" for the iSCSI drive to stay around after you exit. If you still have issues, you might need to point the gateway value in iPXE to the iscsi server, because of a stupid Microsoft iSCSI initiator issue. set net0/gateway 0.0.0.0 usually does the trick. This is because your router might not be set up properly wrt. routing messages back to the local lan segment.
