If you need declaration, then here it is

Public Declare Function WTSQuerySessionInformation _
        Lib "wtsapi32.dll" Alias "WTSQuerySessionInformationA" ( _
        ByVal hServer As Long, ByVal SessionID As Long, _
        ByVal pWTSInfoClass As WTS_INFO_CLASS, ByRef ppSessionInfo As Long, _
        ByRef pBytesReturned As Long _
        ) As Boolean
     
    WTS_INFO_CLASS
    Public Enum WTS_INFO_CLASS
         WTSInitialProgram
         WTSApplicationName
         WTSWorkingDirectory
         WTSOEMId
         WTSSessionId
         WTSUserName
         WTSWinStationName
         WTSDomainName
         WTSConnectState
         WTSClientBuildNumber
         WTSClientName
         WTSClientDirectory
         WTSClientProductId
         WTSClientHardwareId
         WTSClientAddress
         wtsClientDisplay
    End Enum
     
    Public Enum WTS_CONNECTSTATE_CLASS
        WTSActive
        WTSConnected
        WTSConnectQuery
        WTSShadow
        WTSDisconnected
        WTSIdle
        WTSListen
        WTSReset
        WTSDown
        WTSInit
    End Enum

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Thank you PX
This does not show me how to make the API Call as it is already compiled into a Dll.

Public Function QueryUserConfig() As String
   
    Dim bufPtr      As Long
    Dim bufLen      As Long
    Dim tmpStr()    As Byte
    Dim idx         As Integer

On Error GoTo ERR_QueryUserConfig

    CTXQueryUserConfig = False
    cSvrName = svrName & vbNullChar
    cUsrName = userName & vbNullChar
    If WTSQuerySessionInformation(WTS_CURRENT_SERVER_HANDLE, WTS_CURRENT_SESSION, WTSClientAddress, bufPtr, bufLen) Then
        If bufLen > 0 Then
            ReDim tmpStr(bufLen)
            Call CopyMemory(tmpStr(0), bufPtr, bufLen)
            For idx = 0 To bufLen
                'retString = retString & Chr$(tmpStr(idx))
                retString = retString & tmpStr(idx)
            Next idx
           
            Erase tmpStr
        End If
        Call WTSFreeMemory(bufPtr)
        QueryUserConfig = retString
