Computer Cloning with similar SID might cause network problem

Using Disk Image Cloning (e.g. Symantec Ghost) for mass desktop rollout/deployment can significantly saves hours of work and hassle over other rollout method but it might cause major network problem if every cloned system has an identical Computer Security Identifier (SID). This fact compromises security in Workgroup environments, and removable media security can also be compromised in networks with multiple identical computer SIDs.
