The first error had an Error ID of 2214 and a description of:
“Could not load all ISAPI filters for site ‘DEFAULT WEB SITE’. Therefore site startup aborted.”
The second error had an Error ID of 2268 and a description of:
“The HTTP Filter DLL C:\Program Files\Microsoft\Exchange Server\ClientAccess\owa\auth\owaauth.dll failed to load. The data is the error.”
I have resolv this error by copying the C:\Program Files\Microsoft\Exchange Server\Bin\extrace.dll to c:\windows\system32\
