where to look up mac address in sccm properties

As the most important thing for you to know is, that the bytes stored in AD are a little bit “mixed up”. I skip the part about little-endian and big-endian on Intel based systems (see Wikipedia – Endianness).

UUIDs are stored in a different order than displayed.

To get the value you need to do this the other way round and convert each byte into the hexadecimal value and concatenate it. To store a UUID in AD you would need to convert each pair of hexadecimal digits into the decimal value e.g. But working with the UUIDs in Active Directory raises two problems:

As said already, computer objects can also have an attribute netbootGuidwhich can store a UUID. Each object in Active Directory does have an objectGUIDattribute. use “wmic csproduct get uuid” to see the UUID of your computer).Īctive Directory is also using GUIDs for unique identification. The UUID of a computer is stored in the BIOS and can be read via WMI (e.g. Sometimes the GUID is derived from some other values like Serial Number or MAC Address which could result in repetition but generally treat it as unique.

It should, as the name implies, be unique. As this is not as easy as it sounds 😉Ī UUID ( Universally Unique IDentifier) or GUID ( Globally Unique IDentifier) is generally a 16-byte number typically written as a sequence of hexadecimal digits like. So even if not used that often these days I thought it might be worth to enable the webservice to handle GUID values in Active Directory. And I actually like the idea of being able to uniquely identify a computer without the need for another database. During a RIS Deployment it would be able to find an already existing computer object based on this property or create a new computer account with this property (WDS doesn’t use this property anymore). The UUID of a computer can be stored in the Active Directory property netbootGuid. They prestage all computers in Active Directory based on their UUID and he wanted to be able to query AD to get the computer name for their Deployments. A couple weeks ago I got a question from a norwegian fellow.
