We have Exchange Server 2007 that is running on Windows Small Business Server 2008; our owa stopped working and when you try to access it you get this error "HTTP Error 500.19 - Internal Server Error
Calling LoadLibraryEx on ISAPI filter "C:\Program Files\Microsoft\Exchange Server\ClientAccess\owa\auth\owaauth.dll" failed"
I have run this command
cscript.exe adsutil.vbs set W3SVC/AppPools/Enable32BitAppOnWin64 true"
but the issue still occurs.
