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.
1. Un-join from Windows Domain or Active Directory
2. Restart computer
3. Download http://download.sysinternals.com/Files/NewSID.zip and extract into local computer.
4. Run newsid.exe as shown in screenshot below to generate new SID
5. After computer restarted, join the computer back to Windows Domain or Active Directory
Alternatively, you can run the command below with system prompt:
|newsid /a [newname]|
