Question : OWA not working after applying SP3 to Exchange 2007

Last night we applied SP3 to Exchange 2007.  Outlook access is fine but OWA stopped working.  
Just get back "Internet Explorer cannot display the web page" whether outside or inside of our
network.  Looking for troubleshooting steps to see if it is an Exchange, IIS, Certificate, etc. issue.

Answer : OWA not working after applying SP3 to Exchange 2007

Ok, I was able to figure out the problem, although it seems kind of nonsensical.  After trying different settings with SSL on/off, HTTP redirects, etc. it seems that what fixed the problem was just changing the HTTP redirect on the Default web site to include the owa directory.  Somehow this was working in the RTM version of Exchange 2007 but maybe with SP3 the path had to be explictly stated.
