Checking Missing Updates on a Server.

Hi, I created a check.cmd file like this:

@echo off
cls
if exist "%COMPUTERNAME%.html" DEL %COMPUTERNAME%.html
if exist "%COMPUTERNAME%.xml" DEL %COMPUTERNAME%.xml
mbsacli /nvc /xmlout /catalog wsusscan.cab >%COMPUTERNAME%.xml
m2x2h %COMPUTERNAME%.xml %COMPUTERNAME%.html
%COMPUTERNAME%.html

It would give me al the Patches that where missing on the server.
No install was needed and would create an XML file to download the missing
patches.
This because my servers can not go to the internet for any reason at all...
But since the new wsusscan.cab came out, I can not get it to work.
Can someone please help me.
Thank you.
