Ghost Solution Suite

I have installed Symantec Ghost Solution suite V2.5 on a computer, it is running as a ghostcast server, now I am stuck in the process of creating a USB image to be able to boot from client machine and connect the ghostcast.

I tried the ghost boot wizard (both PS dos and Windows PE) and did not work.

Forget DOS, stick with WinPE.

As you have not given much indication of what steps you followed and what exactly did not work, at this point I will just point you at these two articles:

I visited the linkhttp://www.symantec.com/business/support/index?page=content&id=TECH110134 and it has so many options to choose from.

can you tell me the steps to use if I want to create image using network, the computers are connected through a switch and I can ping each other just fine.

Looking back over your original posting, I'm not sure you have made clear exactly which imaging method you intend to use, so I would like to explore this further.

The imaging methods that Ghost offers are both "push" and "pull".

From your posting, it would appear that you want to use the "pull" method, whereby you boot the workstation with a USB device, connect to a server resource, and pull down the image from the server share.

The other supported approach relies on PXE booting the target workstation so that a WinPE boot image is pulled down from the server and used as the boot environment which then installs the image provided by the server.

Either method will require you to create a WinPE image with the appropriate drivers installed for the NIC and SATA chipsets used in your machine inventory.  

If you want to start off simple, you could create a bootable USB hard disk with a copy of the Ghost 32 bit executable on it, and create images locally without involving the network. This would require you to add the SATA drivers only, as the network would not be involved in the imaging process.

If you want to get a bit more familiar with the WinPE environment outside of the Ghost product, this article may help: https://www-secure.symantec.com/connect/articles/readyadventures-winpe

do I use ghost32.exe for 32bits system and ghost64.exe for 64 bits system?  how to create a bootable USB hard disk with ghost? how to create images locally?

Ghost64.exe is only used for hot imaging of 64 bit operating systems. The WinPE boot environment is 32 bit and therefore only requires you to use Ghost32.exe. Since you are booting WinPE, the disk you are imaging is just a collection of sectors, so it does not matter whether the O/S is 32 bit or 64 bit.

Creating a bootable USB device with Ghost Boot Wizard is described in one of the links I posted earlier.
