I’m a novice.  I cannot connect a client computer to our SBS 2003 network. 
When I use the http://SmallBusinessServerName/ConnectComputer web site to
connect a client computer, I’m not successful.  In this scenario, I receive
the following error message:

“You are not authorized to view this page. The web server you are attempting
to reach has a list of IP addresses that are not allowed to access the web
site, and the IP address of your browsing computer is on this list.

HTTP Error 403.6 – Forbidden: IP address of the client has been rejected.
Internet Information Services (IIS).

The client computer I cannot connect was previously joined to the domain.  I
had to do a PC restore and rejoin the client computer to SBS 2003.  I gave
the client computer the same name it had prior, to the PC restore.

I have checked the following:

Under <Server Management>, <Advanced Management>, <Computer Management
(Local)>, <Services and Applications>, <(ISS) Manager>, <Web Sites>,
<ConnectComputer>, <Default.htm>, <Properties>, <File Security Tab>, <IP
Address and Domain Name Restrictions>,<Restrictions>, <Edit>:

By default all computers will be denied access except the following will be
granted: 192.168.1.2 (255.255.255.0)
127.0.0.1

Under <WINS/Active Registration> the client computer I cannot connect has an
active IP address of 192.168.0.26 and the owner is 192.168.0.6.

Under <DNS/Reverse Lookup Zone> the client computer I cannot connect is
listed as 192.168.0.26/br_secretary.xxxxx.local.  XXXXX is not the name of
the server.

I have reviewed the following Article IDs: 908372 and 248043.

It does not make sense that I would have to follow the resolution
instruction steps for 248043.  That is, why should I have to add the computer
IP address every time I want to add a new computer?  It appears that the
notes under 248043 for IP address 127.0.0.1 may apply.  However, there is no
link for instructions regarding how to resolve the local-host issue if that
is the problem.  I’ve never had this type of problem before when I add a
computer to Windows SBS 2003.

Q.  Is this a client computer issue? Or, is it an SBS 2003 issue?  How can I
resolve, this issue.

Thanks in advance for the help.

Show quoteHide quoteWell there's your problem - you've blocked access to it.

192.168.1.2 (255.255.255.0) only allows IP addresses with the first 3 octets
of 192.168.1., and the blocked computer has 192.168.0.

You will need to add the appropriate IP address/range to the granted list to
allow this blocked computer access.
