Exchange 2010 - Blank Screen when accessing OWA

I have just setup a new Exchange 2010 Server on Windows 2008 R2.

I had OWA working fine, and last week Friday installed a UCC Certificate and configured HTTP to HTTPS redirection.

The customer is telling me today that when accessing the OWA site, they get a blank page.  

I examined it, and they are right.  Even from the server itself I get the same thing.    

Per another article I have ensured I have the Exchange 2010 Pre-requisites installed (ran the command from Powershell) but that has not changed anything.  

What can I do to further troubleshoot this?

Does the event viever say anything?
Has it ever worked?
Did it all of the sudden just stop?
Does restarting the services make a difference?
What about trying by IP?
Have you tried more than 1 browser: Note firefox seems to be better at telling you what's actually happening the IE does!
DO IIS logs say anything?
Does it happen with other websites (such as /exchange?)

I may be shooting in the dark here but... what is the current loaded version of it should be 64-bit (asfaik).

All great questions, but it looks like I've figured it out.

Exchange 2010 Rollup 1 was installed over the weekend, either automatically or by another administrator.  Uninstalled - and now OWA works again.


I hope this helps someone else.

Well hey when it doesnt work see what the last applied update was... right...

Start the Command prompt by right clicking it and selecting Run As Administrator.
Re-run the Exchange 2010 Rollup Update 1

That was kinda tricky... I wonder why the installer didnt just elevate the priviledges?  (being that it is a windows update and not just some program) either way though good info...
