no DHCP response to an RIS client

Similar to a previously asked question. I have a W2K network with an RIS server installed & configured and this has been authorised on the LAN's DHCP server. Ticked the "respond to clients box" and the Intel pro ve has a compliant (read newish) pxe rom.

Have copied a w2k pro image (with integrated sp2) to Remote instal folder and all is ready to go except the client never gets a response from DHCP for a lease. Have tried prestaging, not prestaging and triple checked everything according to MS's white paper and all other 'normal' clients on the same LAN are renewing leases fine as they expire but RIS will not talk to the clients I have played with. No DHCP, RIS or DNS error messages in event logs.

Suggestions??

Is the order of events important?

eg. Does installing/configuring RIS server then authorising in DHCP (or vice versa) make a difference.

Thanks in advance

John

You have sort of answered your own question. After installing RIS using the risetup command you msut authorize the ris server to allocate DHCP addresses in active directory. this is done from admin tools/ dhcp. once a ris server is authorized and the client is booted, be sure that the primary boot device on the client is the NIC card and that it is set to boot to the network.Most cards use the CTRL-S to enter the bios feature on teh NIC card itself. once that is set bot the machine and watch carefully. tyou will see a messsage that says "press F-12 for network boot". do so. this will boot you to teh RIS server. In addition if you have any routers on your network they must be configured to forward boot-p requests. good luck.

Done all that, just to be sure have uninstalled, reloaded, resetup and reauthorised RIS server on DHCP server, PXE boot ROM is primary boot device on client. Searches for dhcp but still no response from RIS.

is your DHCP and RIS Server both authorized in Active Directory? both have to be authorized. You state that the RIS server is authorized on the DHCP server....do you mean Active Directory?

At what stage does the RIS process die...BOOTP, DHCP, BINL??????If you don't get past the BootP message, you aren't receiving an IP address from the DHCP server. Are there enough addresses? Is there a router in between the server and the client machine that may not be allowing DHCP packets through?

It was the cisco 3500 switch causing time outs waiting for dhcp requests. Could be spanning tree protocol causing problems on the switch?

Tried the old 10BaseT Hub and it was off and running.

Ta to all for suggestions
