Deploying image using Deployment Solution 7.5

Hi, I just purchased and installed DS 7.5 recently.

My objective for using DS is to re-deploy different images to about 30 PCs on a weekly basis. Basically, every friday night, I will re-deploy image to all PCs to prepare for Monday usage.

I have created 1 image and tested on 1 PC.

My task for the deployment of image includes

1. Boot to Automation

2. Deploy image

3. Boot to Production

4. Apply System Configuration

Tasks 1 and 2 passed but failed at 3.

I realised the PC that was deployed with the image disappear from the DS console. The reason it disappear is because the hostname is the same as the PC that I created the image from.

How should I do to achieve my objectives?
