Hi

Thanks - I think I fixed it - that info didn't work directly but helped! I'd
seen it previously and used the code in an excel *** vba as it's easier to
drive things sometimes that way. While running through the ADSI script that
retrieves the GUID it forced me to try pasting in the GUID - so I
purposefully did it wrong and I got a warning which said that it must be in
the format:

0123456789ABCDEFABCDEFABCD
or re-order in the following format
{67452301-AB89-EFCD-ABCD-EFABCDEFABCD}
So I have forced the read script to use the MAC address as the source
instead of the WMI, I then wrote a bit of code to write the line as the
reordered version and its working for me!

Here is my code: (I use the code from http://support.microsoft.com/kb/302467
inside an excel spread*** as the source with the below added in as
commented)

' REPLACE THIS LINE IN THE DETERMINE SCRIPT szUUID =
"00000000-0000-0000-0000-"&Replace(szMAC, ":", "")
szM = Replace(szMac, ":", "") & "00000000000000000000"
szUUID = "{" & Mid(szM, 7, 2) & Mid(szM, 5, 2) & Mid(szM, 3, 2) & Mid(szM,
1, 2) & "-" & Mid(szM, 11, 2) & Mid(szM, 9, 2) & "-" & Mid(szM, 15, 2) &
Mid(szM, 13, 2) & "-" & Mid(szM, 17, 4) & "-" & Mid(szM, 21, 12) & "}"
