Comments
 
As per Microsoft: "This error is caused by registry restrictions that prevent guest access; it occurs when OWA is using Internet Explorer 5. This error occurs if the following registry key is enabled with a value of 1:
"HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Eventlog\Application\RestrictGuestAccess". This registry key prevents guests or anonymous users from viewing event logs on the server". See ME242900 for more details.
The message itself simply informs that a specific Internet Server API application could not be loaded. This can happen if the file is missing or corrupted. The example below is typical effect of a Nimda virus infection. The "%5c" is a unicode wide character that is used to bypass the internal IIS verification.
