We have 2 Exchange 2010 servers that have been in place and working great for about 15 months. We have 1 Windows 2008 Domain Controller and 2 older Windows 2003 Domain controllers.
Earlier today we had power go out in our area and so all equipment had to be shut down. After power was restored I began to power everything back up. I power on the DC's first and on down the line. After powering everything back up I began to check everything. Email works fine using Outlook but I noticed that I could not logon thru OWA. I get to the logon screen fine but after entering my credentials I immediately get "HTTP 500 internal server error". I don't see any errors or issues. I don't know where to start looking. Can someone help me out? HELP!! thanks
