Refer to this ==> Loop a function?

Yes, you can do it easily with this code :

Option Explicit
Dim MyLoop,strComputer,objPing,objStatus
MyLoop = True
While MyLoop = True
    strComputer = "smtp.gmail.com"
    Set objPing = GetObject("winmgmts:{impersonationLevel=impersonate}!\\").ExecQuery _
    ("select * from Win32_PingStatus where address = '" & strComputer & "'")
    For Each objStatus in objPing
        If objStatus.Statuscode = 0 Then
            MyLoop = False
            Call MyProgram()
            wscript.quit
        End If
    Next
    Pause(10) 'To sleep for 10 secondes
Wend

 Sub Pause(NSeconds)
    Wscript.Sleep(NSeconds*1000)
 End Sub
'**********************************************************************************************
Sub MyProgram()
Dim WshShell
set WshShell = WScript.CreateObject("WScript.Shell")         
On Error Resume Next
   With WScript.CreateObject ("InternetExplorer.Application")     
      .Navigate "http://www.example.com/slideshow"
      .fullscreen = 1   
      .Visible    = 1
      WScript.Sleep 10000

If Hackoo's code doesn't work for you, you can try the following. Not all servers will respond to ping requests but you could just make an HTTP request and see if the server sends a valid response (status = 200).

Function IsSiteReady(strURL)

    With CreateObject("MSXML2.XMLHTTP")
        .Open "GET", strURL, False
        .SetRequestHeader "User-Agent", "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1)"
        On Error Resume Next
        .Send
        If .Status = 200 Then IsSiteReady = True
    End With

End Function
