HP RDP to BL460c on C7000

[Cheshire42]

I'm trying to deploy Server 2008 r2 on a BL460c using PXE booting via the Deployment Console.

While they are attempting to boot via PXE, they stop with the error of 'no boot filename received'.

Using wireshark I have confirmed that the server is reaching the DHCP for the request. The problem appears to be the DHCP server has lost, and is not getting any update, about what PXE options it should be handing out to the servers requesting them.

How do I resolve this?

(will award full points)

Thank you,

The servers failing to PXE boot are all on the same subnet. Other subnets PXE boot fine apparently.

The DHCP server has option 60 set to 'Nortel1', would this be a sign of interference?

Your DHCP scope should have option 66 set to your boot (PXE) server.

The other subnets are probably getting the PXE server location through the "helper" address on the router.

That could explain why servers on other subnets find the PXE server and the servers on the same subnet do not get the PXE server.

Hope that helps...

Perfect, indeed that was the issue.

I dont know why I lost option 66 / why it wasn't being auto-configured, or what changed on which router to remove the helper address (as this subnet didn't always have this pxe issue) but it is fixed all the same.

Much appreciated!
