Multiple PXE Environment
I am currently using RIS for imaging machines and it works brilliantly. However i have just had a provisioning server installed (Citrix) and that means that is broadcasting a PXE boot for the clients to boot from. Which means i now have 2 servers that are trying to do network boots and they both are not doing it.
I have seen some articles on telling RIS to not listen on port 66 and let it use 67 and let the provisioning use 66. However i cant find where to do this!
I know i should just move to WDS but at Easter we are having a complete network overhaul so I don't want to spend the time now doing something I will have to do again at Easter - when i may provision all the new machines anyway!
Does anyone know of how to either make RIS not listen on port 66 or any other way that i could have both servers working!
I am on a flat network with one subnet so i cant do it that way!

Any ideas anyone?
Or could anyone give me a link/guide to vlan off my provisioning services network.
Provisioning server is a virtual server on XenServer on HP Blade in a C3000 enclosure
Blade enclosure connects to a HP2910al-24g switch
Classroom has its own switch connected to above switch, switch is a HP 2650.
Machines connected to that switch directly.
Just a brief outline of my situation if that helps!

Er, RIS doesn't use port 66. It uses the standard ports for DHCP and TFTP and also it's BINL service uses 4011?

Ah ok didnt know that, the article i read seemed to think it did!!
The server that hosted RIS has died this morning so that part of the problem is solved, however i have now built a WDS server. I have found various articles explianing about editing dhcp option 43 to determin which machines look at what pxe server. This should be fairly easy as the provisioned clients mac address' all have the same 8 characters at the start just the last 4 are different.
I want all machines that mac address 44444444???? to point to 192.168.168.14 and everything else to .13
Ive seen this https://www-304.ibm.com/support/docv...g=en&loc=en_US but cant seem to make proper sense out of it!

Can't you tailor your dhcp responses based on Vendor IDs and/or client IDs? Thats how I do it here for my differing SIP phones.

Ended up creating a custom boot menu for WDS with options for WDS, Citrix Provisioning and to exit and continue to boot HDD. Set it so that the Citrix boots automatically after 5 seconds. It works like a charm!!

Ah good. I did manage to find the KB for setting up the Vendor Classe IDs though.
How to Create a New DHCP User or Vendor Class

Thanks for that, ill have a look at that as well as that seems like a more logical way to do it.
Had lots of fun trying to get WDS to call the Citrix Provisioning BIN file but got there in the end!!
