Helping one of colleague from CWA team on the issue where browsing any static content[htm/jpg] is ending with blank white screen on the browser.
That prompted me to look into IIS logs . Here we saw 500 0 1346. As the next troubleshooting step we configure FREB for the 500 error code.
Here we see :
ModuleName IIS Web Core
Notification 2
HttpStatus 500
HttpReason Internal Server Error
HttpSubStatus 0
ErrorCode 2147943746
ConfigExceptionInfo
Notification AUTHENTICATE_REQUEST
ErrorCode Either a required impersonation level was not provided, or the provided impersonation level is invalid. (0x80070542)
Authentication:: anonymous
User from token:: NT AUTHORITY\IUSR
That means we are using Anonymous access and the credential token passed as NT AUTHORITY\IUSR
Resolution provided was to make sure
The IIS_IUSRS group should be in "Impersonate a client after authentication" in the local security policy.
