Random characters after computer name

Question

Hello,
We have a new issue with our agent deployment since we use MDT to deploy our workstations.
When computer register to ZCM some random characters appear after computer name, for example:
Computer name: corporate001
ZCM computer name: corporate001-741132927c2e6f41b5569a9f9409b983
Do you have an explaination?
ZCM Agent is automatically installed after deployment through a .vbs script.
cscript ZCMscript.vbs
Code:
Set objShell = CreateObject("Shell.Application")
objShell.ShellExecute "PreAgentPkg_AgentCompleteDotNet.exe", "-q " & "-x"
strComputer = "." ' local computer
strProcess = "Setup.exe"
Do Until isProcessRunning(strComputer,strProcess)
WScript.Sleep(5000)
Loop
Do While isProcessRunning(strComputer,strProcess)
WScript.Sleep(5000)
Loop
WScript.Quit 0
' Function to check if a process is running
FUNCTION isProcessRunning(BYVAL strComputer,BYVAL strProcessName)
DIM objWMIService, strWMIQuery
strWMIQuery = "Select * from Win32_Process where name like '" & strProcessName & "'"
SET objWMIService = GETOBJECT("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" _
& strComputer & "\root\cimv2")
IF objWMIService.ExecQuery(strWMIQuery).Count > 0 THEN
isProcessRunning = TRUE
ELSE
isProcessRunning = FALSE
END IF
END FUNCTION

Yes, the random number is the "Device GUID".
In your Example there would already be a device called "corporate001" in your zone.
The GUID is added since there cannot be two devices with the same name.
There are reconciliation rules that determine "matches".
Most likely, your rules rely upon MAC and/or SN and this changed instead of relying upon Workstation Name.
No one way is "Correct".
It really comes down to what works for you.
Most likely a tweak of the rules to rely more upon "Workstation Name" may work best for you since I suspect your devices are in a domain if using MDT, which means the names are unique.
