PXE Client could not get IP from DHCP Server

Hi,

The below is scenario for RIS and PXE client,

DC/DHCP, W2K3
RIS: Installed at another W2K3.
Client,OS:WinXP

DHCP is working very well, can assign IP for client PC after these PCs logon
to domain.

In order to test RIS, I start one PC via NIC, PXE mode, but I am always told
the following error:
no dhcp or proxydhcp offers were received

I searched Internet to get the following answers:

?
PXE-E51: No DHCP or proxyDHCP offers were received.
The client did not receive any valid DHCP, BOOTP or proxyDHCP offers.
To resolve this issue, check each of the following network configuration
items:

?
DHCP services are not available on the network to which the
PXE-enabled NIC is connected.

?
A DHCP proxy or IP helper address is not configured for the
subnet on which the PXE client is connected.

?
The switch port connected to the PXE NIC is running Spanning Tree
Protocol, EtherChannel Protocol, or Port Aggregation Protocol and is thus
not activated immediately when a link is detected. This forces the DHCP
request from the PXE client to timeout.

?
DHCP is available on the network, but PXE is not.

?
The network cable is not attached to the PXE-enabled NIC on the
target server.



Interesting, this PC can get IP address after rebooting OS from hard
disk.

Make sense please.

What's wrong in my operation and DHCP configuration.

BTW, some people said 60 class ID in DHCP configuration, is it true?

Thanks,

DHCP Configuration
1.. Open the DHCP control panel from administrative tools.
2.. Expand the server you are wanting to configure. Expand the
"Scope" folder. Right click on "Scope Options" and select "Configure
Options".
3.. Put a check mark in "013 Boot File Size" and enter the file size
in 512 octet blocks. Example, your boot image file is 12 KB (kilobytes).
Convert 12 KB to bytes (12288). This must be exact, don't just multiply 12
by 1000. Divide the file size in bytes by 512 (12288 / 512). Enter the
resulting number (24) in the text dialog that is enabled when you put a
check in 013.
4.. Put a check mark in "043 Vendor Specific Info" and enter the
following binary value: 01 04 00 00 00 00 ff.
5.. Open a command window and type the following:
6. c:\>netsh

7. netsh>dhcp

8. netsh dhcp>server \\server_name

9. netsh dhcp server>add optiondef 60 ClassID String 0

10. netsh dhcp server>set optionvalue 60 STRING PXEClient

11.. Put a check mark in "066 Boot Server Host Name" and enter the
IP address of the server.
12.. Put a check mark in "067 Bootfile Name" and enter the name of
the boot image file.
13.. (Thanks to Mark McRitchie for this step.)
If you use the Linux-based boot disk, you can set the boot disk's
defaults (user name, password, share) via DHCP option 233. Open a command
prompt and type:

netsh dhcp server add optiondef 233 Unattended String 0
comment="Unattended dhcp info"

Go back to "Scope Options", select configure options, put a check mark
next to the new entry, and fill in the boot disk options you want to use
(e.g., z_user=username z_pass=sekrit z_path=\\myserver\myshare).

14.. Right click on the server name in the DHCP control panel, go to
all tasks, and select "restart".
15.. Go back to scope options and verify that all the information is
there. You should see the five entries on the right. They should look like
this:
16.

17. 013 Boot File Size Standard 0x18

18. 043 Vendor Specific Info Standard 01 04 00 00
00 00 ff

19. 060 ClassID Standard PXEClient

20. 066 Boot Server Host Name Standard Server IP
address

21. 067 Bootfile Name Standard bzImage
(boot file name)

If any of the options do not match these, double-click on the option
and change the value. More than likely option 060 will be wrong. Change it
so it looks like above.
