Update Rollup 1, Exchange 2010 and OWA failing

When simply applying the Update Rollup 1 for Exchange 2010, you might end up with a blank logon screen at your CAS servers when you want to reach OWA.

When opening up the details of the error message, the following text is shown:

Webpage error details
User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; WOW64; Trident/4.0; SLCC1; .NET CLR 2.0.50727; .NET CLR 3.0.30729; .NET CLR 3.5.21022; .NET CLR 3.5.30729)
Timestamp: Wed, 23 Dec 2009 15:34:46 UTC
Message: Syntax error
Line: 1
Char: 1
Code: 0
URI: https://localhost/owa/14.0.682.1/scripts/premium/flogon.js

How to solve it?
Start an Administrative Exchange Management Shell
Type ii Exchange2010-KB976573-x64-en.msp
Close the Exchange Management Shell and finish the patch.

NB If you do not run the Exchange Management Shell as an Administrative prompt, you will get an error regarding a premature ending of the patch..

    It works even with Updare Rollup 3 (Exchange2010-KB981401-x64-en.msp). Thanks for the solution!!!

    You only forgot to mention where to find Exchange2010-KBxxx-x64-en.msp.

    For all who have the same problem, you can find the Exchange2010-KBxxx-x64-en.msp in the directory C:\Windows\SoftwareDistribution\Download and then search in one of the subdirs (in my case it’s the “5ff337aeebffa0cfd260eaa6e001afb6” directory). You’ll find the .msp file in a directory called img.
