RIS - DHCP & Resolve

[Matthew Jones]

No - President Bush isn't looking for Resolve - I am!

I've configured RIS and all has been fine.
Except, 1 client says it can not resolve the IP Address when booting from
the RIS Boot diks.
I've updated the RBFG.exe file and re-created the boot disk. - No Go!!
I've attempted to populate DHCP with router info {should I put the RIS
Server address?)

What else am I missing????

Thanks in advance..

Resolve what IP address? It is getting an IP though, right?
Just for my info, are you plugged into a switch or a hub? If a switch, what
brand/model?

Jeremy - Thanks for the reply.

Here's the config.
I am plugged in to a Cisco 3600 switch.
I've run dozen other clients (dells) through this and have not had any
problems. This client one is a Compaq.

I am getting an IP Address but it's a bogus one.
31.x.x.x or something. The LAN that I am on is 192.168.1.x - The
hosts/servers are on the same sub-net.

This one has be baffled. I do know there's a professional version of RFGB
but I don't know for sure if it will resolve the issue.

Thanks for any suggestions you can offer.

Since you have most of your machines working, I wouldn't change too many
things. Delete the lease that the Compaq has from your DHCP server if there
is one.

Do you have any misc devices like wireless hubs and the like that might be
handing out addresses? We see them from time-to-time especially with Apple
Airports which may have been installed by a novice.

I assume that you have checked the DHCP helper addresses in your router
interface that connects to the Compaq?

If your machines are all on the same subnet then you don't need to configure
DHCP options to name the RIS Server.

What nic does the Compaq use? Is it an older computer? You might need to
update the PXE Rom on the nic.

This is a common problem with switches. Because of the spanning tree
protocol, it takes time to get a link on the switch.
In the cisco switches, there is an interface setting to disable the spanning
tree protocol. I can't remember the exact command, but it something like
fast link or something. I would enable fast link or turn off spanning tree
(unless you need it). This will make your link almost instant. I would
guess the timeout on the Compaq is shorter than on the dell computers.

I have had this issue with the RBF/PXE emulator also. It just depends on
the timeout.

What is happening is it takes too long to get a link which then causes you
to not get a DHCP address (obviously because you are not on the network).
If you don't get a DHCP address, then you get an error like the one you
mentioned.
