AuthHosts
The AuthHosts setting is, unlike the other
settings, a REG_SZ string. It is used to specify
a set of IP address templates which incoming
connections must match in order to be accepted.
By default, the template is empty and
connections from all hosts are accepted. The
template is of the form:
+[ip-address-template]
?[ip-address-template]
-[ip-address-template]
In the above, [ip-address-template] represents
the leftmost bytes of the desired stringified IP
address. For example, +158.97 would match both
158.97.12.10 and 158.97.14.2. Multiple match
terms may be specified, delimited by the ":"
character. Terms appearing later in the template
take precedence over earlier ones. e.g. -:+158.97:
would filter out all incoming connections except
those beginning with 158.97. Terms beginning
with the "?" character are treated by default as
indicating hosts from whom connections must be
accepted at the server side via a dialog box.
The QuerySetting option determines the precise
behaviour of the three AuthHosts options.
Local machine-specific setting.

QuerySetting
The QuerySetting allows individual users to
tailor the degree of paranoia expressed by the
per-machine AuthHosts setting. It is a DWORD
value ranging from zero (maximum availability)
to four (maximum security). The following table
indicates how the value affects the AuthHosts
behaviour:
0 - +:Accept, ?:Accept, -:Query
1 - +:Accept, ?:Accept, -:Reject
2 - +:Accept, ?:Query, -:Reject [Default]
3 - +:Query, ?:Query, -:Reject
4 - +:Query, ?:Reject, -:Reject
By default, value 2 (Obey AuthHosts) will be
assumed. Local & global per-user setting.

QueryTimeout
The QueryTimeout setting indicates the number of
seconds for which the Accept Connection dialog
(see AuthHosts and QuerySetting options) will be
displayed before rejecting the incoming
connection automatically. Local & global
per-user setting.

What the registry looks like...

[HKEY_LOCAL_MACHINE\SOFTWARE\ORL\WinVNC3\Default]

"QuerySetting"=dword:00000003
"QueryTimeout"=dword:00000014
"AuthHosts"="?xxx.xxx,?xxx.xxx" <- Your networks IP address[s]
