thanks Rogue Spear, i'll give those great tips a shot ASAP. that is excellent, thank you very much. i found an article that mentioned you could 'pre-stage' the pc you are RIS'ing by adding the computer to Active Directory first with the computers GUID and making it managed etc etc however, after RIS'ing that pc it still picked up the GUID from the image being deployed to it, and then when i checked that computers AD object it had updated with the incorrect one. this is frustrating because every RIS doco/article i found before attempting this, and even the official MS KB article mentions nothing about having to perform some sort of sysprep to strip unique system info from the pc you plan to create the RIS image from. at the end there's a small mention of the GUID but it doesn't really link to any other articles to explain itself in more detail. even if i change the GUID for the imaged PC in Active Directory to and then check the pc using the cmd "wmic csproduct get UUID" it still shows the incorrect one so AD doesn't seem to be able to update the computers SMBIOS with the info i'm telling it to. oh these are DELL pc's as well. there's nowhere to find the GUID before attempting to RIS the pc, but even then it only tells you the incorrect one that it's attempting to give to it, this is where it says "an identical GUID exists on the network" and it gives you the option of proceeding but cleaning it up in AD afterwards. this is what im trying to find out how to do, clean it up afterwards
