Duplicate GUID during RIS install

Question

I am getting the 'Duplicate GUID' error during an RIS install on a GX270. When I boot and press F12 and boot the the NIC the Intel PXE loads and give me a GUID. I have confirmed the same GUID on two pc's during this process. My question is where does the GUID come from? My understanding was it came from the bios but if that was true then the duplicate guid ID problem shouldn't exist. Does it possibly come from the DHCP Server? Does anyone know the low-level process that is ocurring here and how I can resolve this problem? Is there a bios utility to change the GUID? I have seen suggestions to change the guid in Active Directory using ADSIEdit. Is it that simple and will doing this change the guid that shows in the bios? Any thoughts on this would be much appreciated.   Thanks Dave

'If you use the same adapter to do RIS installations on multiple machines, you will get a 'duplicate GUID' error.' Check this link: http://www.mcpmag.com/columns/article.asp?EditorialsID=509  Mike

Hi thanks for the reply. I did see this article but I guess I am confused about the 'adapter' part. This is the adapter on the client correct? If two GX270's are PXE enabled and have different MAC address's. (OR Should) Then you should never see the duplicate ID error right? However if you use the RIS Boot disk then this may happen. Thats what I get from the article anyway. It seems that changing the MOBO would or should work. But I have had this happen to me with more than two pc's so I'm not sure what to think. Of course the GX270's mobo is notoriously bad and I have had many fail on me, maybe something happened during production.
