Script Help

Need help logging into the web interface of my WhatsUP gold server for an overhead display in our IT dept.

Essentially I want the script to open IE, navigate to our servers web address, login to whats up, then kill IE and start the process over. ( only because the web interface times out after about 10 mins and logs you out )

Currently I have this:

$user='admin'
$pass='squirrel69'

#include <IE.au3>

Dim $oIE = _IECreate('about:blank', 0, 0)

With $oIE
    .Left = 0
    .Top = 0
    .Menubar = False
    .Resizable = False
    .StatusBar = False
    .TheaterMode = True
    .Toolbar = False
    .Visible = True
EndWith

_IENavigate($oIE, 'http://srv13app8/NmConsole/CoreNm/User/DlgUserLogin/DlgUserLogin.asp')

I AM STUCK please help !!
