Introduction |
Not so many people prefer to do
installations remotely, specially for a Firewall Like
ISA Server that is well known to have a Default rule
upon installation to deny everything that passes
through it. But for those who wish to do such
installation, go on , its safe, and you will be able to continue having remote access to the machine after ISA Server is
installed

Configuration on Windows Server Before
Installing ISA Server
Before installing ISA Server remotely, we need
to be able to Remote Access to the server we want to
install ISA Server on.
so
our pre-requisites
are
:
-
To enable Remote Desktop, Right
click on My Computer > Properties
> Click on the Remote Tab and enable the
checkbox where it says Enable Remote Desktop on
this computer

-
Next , if the Windows Firewall is enabled on the Windows
Server Machine, you will need to allow two
Exceptions:
* Files and Printer Sharing
* Remote Desktop
To do this, click on Start >
Control Panel > Windows
Firewall

-
Click on the Exceptions Tab

-
Enable Both Files and
Printer Sharing & Remote Desktop

Installing ISA Server From
the Remote Machine
-
In this example,
I used my
personal Laptop which has MS Windows VISTA Ultimate on
it.
To start the Remote Desktop Connection, lets go to
Run
-
Click on Start > Then
Run , or if
you prefer keyboard shortcuts, click on
Windows Key + R
-
The Remote Desktop Connection application can be opened
using the command mstsc, Click Ok

-
Enter the Name of the Server you are going to
connect to , in this example my Server name is elmaj-srv ,
Click Connect

-
You might receive a Credentials page, enter the username
and password so that you grant access to the remote
machine, Click Ok

-
Once you enter the credentials, the desktop of the
remote server will open , if you have someone to put the
ISA Server CD in the target machine, tell him/her to do
it now, or as you remember I enable File and Printer
Sharing in the Windows Firewall Exceptions, I did this
so that I would be able to transfer files from my
machine ( Laptop ) to this Server over the Network
( \\elmaj-srv ), having
this I would be able to transfer the content of
the ISA Server CD from my laptop to this server
-
If you had someone to
insert the ISA Server CD into the server, the CD
should auto run and you will have the following image,
or if you transferred the files over the network, open the
folder to which you transferred the files and double
click on ISAAutorun.exe
-
Click on
Install ISA Server 2006

-
You will get the
Welcome to the Installation Wizard for
Microsoft ISA Server 2006
page, click on Next

-
Read the terms and Accept it, otherwise do
not :)) , then click Next

-
Enter the
Product Serial Number that you got when you
purchase the CD

-
Choose a setup type,
I will choose Typical and click on
Next

-
On the
Internal Network page, click the
Add button to
enter your Internal Network Range

-
Click on
Add Range button to manually specify the range
of your Internal Network

-
Enter your Internal Network Range , click
OK

-
The Internal Network range will be displayed in the
Internal Network page, if you need to change it , click
the change button, otherwise click Next

-
To Allow previous Firewall Client versions to
communicate with ISA Server 2006, enable the box Allow
non-encrypted Firewall Clients connections, click
Next

-
The
Services Warning page will display to you the
services that will be restarted or disable during
installation

-
Here is the page that we are waiting for so long, the
System Policy Configuration page.
In this page, you will be notified that the IP of the
machine you are working from ( My Laptop that has an IP
192.168.1.73 ) will be added to the Remote
Management Computer Computer List
In a regular installation, you would
not get such
page, only when you are remotely installing ISA Server,
your Machine will be added to the Remote Management
Computer List, be informed that once ISA is installed
you will grant access to the ISA Server to access it
remotely, if this option was not included, you would be
denied by the default rule which denies everything
passing through ISA Server, Click Next

-
The
Core Components, Additional Components and the
System Initialization will take place


-
After the System Initialization finishes, your screen
will blink and your RDP Session will be disconnected
for a couple of seconds, shortly you will be
automatically granted the RDP Session again, click on
Finish

-
Once the Installation finishes, a page will open and you
can have few minutes to read it.

-
Close the
Microsoft ISA Server 2006 Setup page by
clicking on the Exit button, and we are
done.

-
To Open
ISA Server Management Console, click on
Start >
All Programs> ISA Server Management

-
Open the System Policy ,
From the Right Pane > Click on Tasks
Tab > Click Edit System Policy

-
Go
to Remote Management Configuration
Group

-
Click
on any option below the Remote Management
Configuration Group, and you will notice that in the
From Tab, there is a Remote
Management Computers Computer List, click on
it and click on the Edit Button,
you will notice that the IP of the machine I used (
My Vista laptop ) is included into this Computer
List, and that is how we were still able to remote
access to ISA Server After installation was
completed.

Summary
In this article, we installed ISA Server 2006
from a Remote machine, and we were able to continue
working on the server that we installed ISA Server remotely, and that is because ISA Server will detect that it is
being installed Remotely, and will automatically add the
IP of the machine you are working from to the Remote Management Computers Computer
List that is used in the System Policy to allow remote management of ISA Server
