You can change the identity of your computer to avoid authentication problems whenever there exists the same computer identity within a network. This can be helpful, whenever a system image is created on several computers within the network. The disk of a fully installed and configured Windows computer is transferred onto another computer.
Although this cloning method does save time and effort the problem that each cloned system has an identical computer SID might arise. This influences the security in working group environments. In addition, the security of transfer media might be inhibited in networks with many computer SIDs.
Note: If an error occurs while changing the current computer SID, then we recommend resetting the registration structures SECURITY and SAM.
- Under Tools click Change computer identity.
- Load the computer’s non-active Windows system.
- Then, enter a computer name for your computer (Give new name). Change saves your settings and the computer identity after you have changed them. Close cancels the dialog without applying any changes.
