It depends on the application.  Although you don't say which this
warning applies to, your question suggests it's an IIS server.  If so,
take a look at Microsoft Knowledge Base Article 245030, available as
<http://support.microsoft.com/default.aspx?scid=kb;en-us;245030>, and
note the plugin classifies ciphers with less than 56 bits as weak; those
with between 56 and 89 inclusive as medium strength, and those with 90
or more as strong. 

Keep in mind there may be reasons to support export-grade ciphers (eg,
the client base is international).
