Hi,

For this issue, we can simulate the problem by running the VB script (with the same user context as the monitors runs it) manually to check if the registry hive is accessible for further trouble-shooting. Below is just a sample for your reference:

  Const HKEY_CURRENT_USER = &H80000001  
  const HKEY_LOCAL_MACHINE = &H80000002  
  Dim strComputer  
  strComputer = "."  
  
  On Error Resume Next  
  Dim oReg, strKeyPath, strValueName, dwValue  
  Set oReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\default:StdRegProv")  
  strKeyPath = "System\CurrentControlSet\Services\NTDS\Parameters"  
  strValueName = "Strict Replication Consistency"  
  oReg.GetDWORDValue HKEY_LOCAL_MACHINE,strKeyPath,strValueName,dwValue  
  WScript.Echo "Strict Replication Consistency: " & dwValue  
    
  Dim strError  
  If (Err.Number <> 0) Then  
    strError = "Failed to connect to registry hive HKLM." & vbcrlf   
    strError = strError & "Verify that the agent has access to view the registry."  
    WScript.Echo strerror  
  End If
