GUID Not Valid
The globally unique identifier (GUID) query you entered is not valid. Use one of the following formats to enter a GUID:
- Each pair or characters is called an octet. Work with the GUID from left to right.
- Take the first 4 octets and reverse their order: 01234567 –> 67452301.
- Take the next 2 octets and reverse their order: 89AB –> AB89.
- Repeat for the next 2 octets: CDEF –> EFCD
- The rest of the octet string is identical for both formats so just add a hyphen: ABCDEFABCDEFABCD –> ABCD-EFABCDEFABCD
- PXE boot screens always display octet string GUIDs (except Hyper-V VMs)
- Active Directory Users and Computers always displays the GUID in GUID string format.
- Active Directory Users and Computers accepts both octet string GUIDs and GUID string GUIDs, but will always convert to GUID string when displaying.
