Not surprising at all. PXE reports the contents of the UUID array, while
Win32_ComputerSystemProduct contains the Windows GUID.
Here is how it maps:
#
# guidstr
#
# takes a 16-byte array and turns it into the standard
# text guid format.
#
# try as i might, i couldn't get system.guid in .net
# to work.
#
# 3,2,1,0
# 5,4
# 7,6
# 8,9
# 10,11,12,13,14,15
#
function guidstr([byte[]]$b)
{
if ($b.length -ne 16)
{
return "";
}
$f = "{0:x2}";
$str = ($f -f $b[3]) + ($f -f $b[2]) + ($f -f $b[1]) + ($f
-f $b[0]);
$str += "-";
$str += ($f -f $b[5]) + ($f -f $b[4]);
$str += "-";
$str += ($f -f $b[7]) + ($f -f $b[6]);
$str += "-";
$str += ($f -f $b[8]) + ($f -f $b[9]);
$str += "-";
$str += ($f -f $b[10]) + ($f -f $b[11]);
$str += ($f -f $b[12]) + ($f -f $b[13]);
$str += ($f -f $b[14]) + ($f -f $b[15]);
return $str;
}

Subject: RE: Enumerate GUIDs for all comps in an OU
Here's a real mind screw:
Win32_ComputerSystemProduct has a UUID which suggests on one PC:
54674461-7948-1000-9A34-000E0C6A5779
When it boots, the PXE code says:
61446754-4879-0010-9A34-000E0C6A5779
Notice the first 3 groups are the same numbers, but just mixed up?
What is that all about?
Thanks!

Hey Michael,
I am using CIM Studio to look for this, and call me dense but I can't find
it J
Can you push me along a bit here?
Thanks!

The SMBIOS GUID. Which is properly a CIM UUID (and that's what SCCM calls
it).
RIS/WDS doesn't care about the objectGUID. That's a crappy error message.
It's pretty easy to scan through AD using vbscript or PS and retrieve all
the UUIDs with WMI.

So when a cheap mobo has a dupe guid with another, which guid in AD does RIS
say "A GUID for this computer already exists in Active Directory."?
Any idea?
Thanks!

The SMBIOS GUID used by WDS is tied to the motherboard, not to the AD
object. Sorry, I didn't know that that was what you were looking for.
You get that from WMI (for compliant motherboards). For example:
PS C:\Users\Michael> gwmi win32_computersystemproduct | fl uuid
uuid : 61383066-3835-3962-6635-001B384EE42B
PS C:\Users\Michael>

Hey Michael,
Am I missing something here? I thought machine's deployed via WDS/RIS used
the GUID as reported by the wkst?
During the post I can see them and they are very different from the guid's
enumerated by adfind. I have not blacklisted any guids yet, and none of them
correspond to the mac address that I can visual see which would be a result.
The deployments were CD based, not image based.
Any ideas?
Thanks!

Adfind -default -b ou=ouname -f name=* objectGuid
?
If you actually want vbscript for it, I can hunt it down. But it's a LOT
more lines.

Anyone know a query I can do through vb for this?
Thanks!
