22.13 Warning Log
The Warning log displays warning messages about errors of little significance. Warnings can
display for example reports about invalid user login (invalid username or password), error in
communication of the server and Web administration interface, etc.
Events recalling warning messages in this log do not seriously affect WinRoute functionality.
However, they can point at current or possible problems. The Warning log can help if for
example a user is complaining that certain services are not working.
Each warning message is identified by its numerical code (code xxx:). The following warning
categories are defined:
1000-1999 — system warnings (e.g. an application found that is known as conflicting)
2000-2999 WinRoute configuration problems (e.g. HTTP rules require user authen-
tication, but the WWW interface is not enabled)
3000-3999 warning from individual WinRoute modules (e.g. DHCP server, anti-virus
check, user authentication, etc.)
4000-4999 license warnings (subscription expiration, forthcoming expiration of
WinRoute’s license, ISS OrangeWeb Filter license, or the McAfee anti-virus license)
Note: License expiration is considered to be an error and it is logged into the Error log.
