Reading the SCCM Client GUID

Recently I encountered an issue with the SCCM client GUID missing from the  %windir%\SMSCFG.INI file. We wanted to write a script to put the GUID back, so I was asked how to read the SCCM Client GUID from a script or command line.

VBScript:

Set objWMIService = GetObject("winmgmts:\\.\root\ccm")

Set colItems = objWMIService.ExecQuery("Select ClientID From CCM_Client")

For Each objItem in colItems

Wscript.Echo "Client ID" & objItem.ClientID

Next

WMIC via commandline:

wmic /namespace:\\root\ccm path ccm_client get clientid

PowerShell:

Get-WMIObject -namespace root\ccm ccm_client clientid | Select-Object clientid
