Exchange 2007 OWA authentication failure

Hi Experts,

I need some urgent help. I have been trying to get owa to work all day with no luck.

I upgraded the exchange 2007 server to SP3 this morning and since then OWA does not work. Ihave done everything i found on the net on ways to fix it. Things like remove OWA vir dir and create a new one. Check all permissions, make sure FBA is enabled make sure the correct internal and external URL's are there.

The system is on SBS 2008 and is a single sever with all roles installed. The system worked fine until i upgraded to SP3.

If i browse to my url, http://webmail.companyname.co.uk it used to redirect me to https://webmail.comapnyname.co.uk/owa, its a config thing i did. This doesnt work now.

If i go to https://webmail.companyname.co.uk/owa i get a blank page.

If i try test-owaconnectivity with a current user i get authentication failed.

I have a 3rd party cert with 5 sub alt names and is installed and working correctly.

HELP please.

Some of it makes sense but i have tried all of that, i also dont have a default website. All owa and other exchange items are under SBS Web Applications website. I just tried to remove the owa vir dir again and am now not able to create a new one. This is geting worse.

This is a very big problem. SP3 has royally screwed my server up.

i have moved on, created a new cas server and installed what i needed there. SBS 2008 sucks!!! This question can be closed.

did not get any good responses as to why OWA on SBS 2008 failed, created a new CAS server and took away the role from SBS so therefore solved my own problem
