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 asp.net? 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.

HA!

I hope this helps someone else.

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

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...
