OWA brings up logon screen but after login gives http 500 internal server error

    Question

  • 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
