S 4.109 Software reinstallation on workstations
Initiation responsibility: Head of IT, IT Security Officer
Implementation responsibility: Administrator
Problems with the operating system or applications which can only be resolved through user support occur relatively frequently on workstations. These problems can be caused, for example, by software errors, configuration changes, installation of new software or computer viruses.
To avoid administrators having to spend a lot of time troubleshooting on workstations in connection with the problems described above, a software reinstallation of the default configuration should be performed.
First of all, the computer must be uniquely identified. Starting from this identification, it is then necessary using appropriate documentation or a program to establish precisely what software is installed in what configuration on exactly this computer. It is helpful here if the IT systems are very similar, at least in areas with similar assigned tasks.
It is recommended that the workstation hard disk is re-formatted and the required software and data is then reinstalled.
A software reinstallation can be performed in various ways. For example, there are special programs which will export a predefined configuration from a server onto the workstations which are to be reinstalled. It should be noted that this kind of work is generally time-critical in two ways: On the one hand, it is desirable that reconfiguration is effected as quickly as possible so as to make the IT system available once more, while, on the other hand, the network loading must be minimised. This is especially important in the case of training computers or PC pools.
It is of course also possible to perform the reinstallation "manually". To do this, a default installation should be performed first of all. The special features of the individual computers, such as special device drivers, additional configuration files or special software, are then copied. However, this requires that they are available preconfigured, e.g. on the network or on mobile data media. An up-to-date anti-virus program must then be run.
Review questions:
- Is a procedure defined to be able to reinstall workstations quickly if required?
- Is it possible to clearly identify the IT system concerned and the required configuration when reinstalling IT systems?
- Is the reinstallation process designed in such a manner that it is possible so as to make the IT system concerned available once more as quickly as possible?
- Is the reinstallation process designed in such a manner that the organisation's network loading is minimised?
