I was referring to the local guest user account on the server. If the
local guest account is enabled on the server, this plugin flags the
issue but the local administrator password being blank doesn't flag an
issue. If I disable the local guest account, it will alert me that the
local administrator password is blank.

I am new to Nessus and am running some basic scans to get a grasp on it.
I have two plugins enabled(SMB blank administrator password and SMB
guest account for all users) but I am only getting results for one. If
I check the log it says "required key missing" on the plugin that didn't
run. Here is my targeted server configuration and the nessus output.
Blank admin password and guest enabled = Results for SMB guest account
for all users
Blank admin password and guest disabled = Results for SMB blank
administrator password

In the case of these two plugins, you'll see this message in the log
if you have optimization turned on and the plugin doesn't report a
problem.
Here is my targeted server configuration and the nessus output.
Blank admin password and guest enabled = Results for SMB guest
account for all users
Blank admin password and guest disabled = Results for SMB blank
administrator password
With the "Guest only" module for local accounts, aren't network logons
are automatically mapped to the guest account? How would you be able
to determine if a particular local user, such as Administrator, is
missing a password in that case?

Thank you Mr. Theall. So, actually, how Nessus perform the particular
process after finish loading a plugin? For example, like you said
before, they send request to a port. How Nessus do this kind of sending?
Which part do this, Nessus or plugin? Thanks~

I am trying to understand how Nessus identify a host is a web server

identification been implemented in the source code? Or Nessus do
this by using some specific plugins?
Service detection isn't as black and white as this -- a host isn't
identified as being a web server or workstation. Instead, Nessus
attempts to identify the services running on the various ports(s)
being scanned so in theory it will catch the web server running along
with MySQL, SSH, and SMTP.
Nessus uses plugins for this. Some such as #10330, #17975, and #11153
are fairly general - they send a request to a port and make a
determination based on the banner or the results returned. Others are
specific to a single application / protocol.
