Nothing is returning from the .read call ??
Any ideas on why this isn't working and what I should do to enable it??

Private Sub Command1_Click()

    Dim objwsh As New WshShell
    Dim sInput As String

    Set objWSHexec = objwsh.Exec("ipconfig")

    While Not objWSHexec.StdOut.AtEndOfStream
          sInput = sInput & objWSHexec.StdOut.Read(1)
         If InStr(sInput, "Press any key") <> 0 Then
            Exit Sub
         End If
    Wend
   
End Sub

Try this

Set objShell = WScript.CreateObject("WScript.Shell")
Set objExecObject = objShell.Exec("%comspec% /c ipconfig.exe")

Do Until objExecObject.StdOut.AtEndOfStream
    strLine = objExecObject.StdOut.ReadLine()
    strIP = Instr(strLine,"Address")
    If strIP <> 0 Then
        Wscript.Echo strLine
    End If
Loop

In WindowNT or high %comspec% returns cmd.exe
In Win95 or higher %comspec% returns command.exe
