User's guide O&O DiskImage Change computer identity
Change computer identity
You can change the identity of your computer to avoid authentication problems whenever the
same computer identity is already being used within a network. This can be helpful whenever a
system image is being rolled out onto several computers across a network, meaning a fully installed
and configured Windows computer is transferred onto the drives of another computer.
Although this method does save time and effort compared to other kinds of duplication, there is a
problem arising with each cloned system having the identical computer SID. This influences the
security in working group environments. In addition, the security of transfer media might be
inhibited in networks with many computer SIDs.
To avoid this problem, O&O DiskImage provides an option for changing the computer identity.
Note:
The SID can only be changed when you run O&O DiskImage from the bootable medium (Start CD)
and not during normal Windows operation.
Note:
If an error occurs while changing the current computer SID, we recommend resetting the
registration structures SECURITY and SAM.
