It is a special feature
of the Symantec-Ghost-Suite that will allow you to put an image on a
single or multiple computers over a network simultaneously, very handy.
Before you start you will need a network and a computer to act as the
If you can afford it there is also a system called the "Octopus" that uses a
network or a multiple drive cable attachment that will do this also. I have used
one type of system like this and it is quite expensive, large computer
manufactures use this type of system to put their "image" on hard drives prior
to installation in the computers being built.
Two companies I worked for used Ghostcast to image multiple computers at one
time, one was a rental company and the other was a major bank. The companies
found out that imaging multiple computers use a lot of the available network bandwidth, that is if there is other network traffic on the network when the
imaging process is ongoing the network will be very slow. To keep this from
happening the companies had a separate network for the Ghostcast server and the
client computers receiving the image.
A 100 MBPS network could service up to 40 computers at one time but it would
be slow, we found that the max of 30 computers could be accommodated in a
reasonable time. I wasn't there when 1 GBPS came out but I would think that
there would be a large improvement in the speed that the image could be
delivered to a computer and the number of computers being imaged at one time
would be over 30.
With a separate network for the Ghostcast imaging process you will have
better security for those that need increased security. Depending on your space
you could have a KVM switch for multiple computers, one tech could do all the
imaging by their self.
With the Symantec Ghost Suite you will find all the tools you need to make
bootable devices for connection to the Ghostcast server. Once you have your boot
devices tested you are ready for the next step.
Before you can deploy your new computers or reimage a set of computers you
will need to make the image.
By now you should be able to create a Ghost image if not

To save yourself or your department some time these are the steps I use when
creating an image before deployment:
All computers have to be the same make and model or the image will fail, if
you are using different computers and make one image those that are not the same
make and model as the computer the image was made from will BSOD...
Setting up the new test computer:
- Install the Operating System.
- Run all the updates.
- If the computer has multiple drive partitions set your security per your
- Optimize the Operating System.
- If you network doesn't use DHCP for assigning IP addresses get a static IP
that is outside the range of the current network address. (This will insure
that when you load the image on a computer that is connected to the network it
doesn't cause a duplicate IP error, older switches will crash when a duplicate
IP is detected).
- Install all the user programs.
- Do any company standardization and customizing.
- Put the test computer into your Domain and test the company GP's to insure
there aren't any conflicts.
- Test all the programs, better yet have a user use the computer for a while
to insure there aren't any unforeseen problems, you are putting a lot of time
in making the image, better to have a known good image than a mediocre image
that needs to be fixed frequently.
- Make your image.
You may want to make an ISO of the image also for techs in the field, having
the ISO on a secure sever for download each tech can make their own CD/DVD for
install in the field.
Once you have your network, Ghostcast server, and image all you need are the
computers to send the image to, then deploy them to your users.
When you deploy the image to multiple computers you can use the tools in the
Symantec Ghost Suite to change the computer name and SID or you can find
the SID Changer utility on Microsoft Tech Net. If you don't change the computer
name then the SID you will have name and SID conflicts when you try to bring the
new computer in to your Domain.
This is a lot faster than doing one or two computers at a time when you have
a Ghostcast server to do 30 or more at one time. This makes deploying a new
computer to your users faster with less headaches.
Question: Can you use this system on a small network for deploying or re-imaging of computers? Yes, indeed. You do have to consider the cost of the
Symantec Ghost Suite, that is would it be cost effective to buy the suite and
have a computer with the software installed to do a computer once in a while vs
having a bootable device and the image on an external hard drive or CD/DVD?
