Making Permanent Configuration Changes with BigFix
In order to make any permanent configuration changes in the workstations, such as updating critical
patches and/or virus definitions, Deep Freeze must be disabled by rebooting the workstations into a
Thawed state. The updates can then be deployed through BigFix or an Enterprise antivirus solution.
One method to accomplish this is by making updates and critical patches strictly during the Maintenance
Period.
Another way is using BigFix to run a batch file to set the workstations into a Thawed state and, after the
updates have been installed, another batch file to return them to a Frozen state.
The command used to reboot the workstations into a Thawed state is:
DFC password /BOOTTHAWED
.
The command used to reboot the workstations into a Frozen state is:
DFC password /BOOTFROZEN
.
The Command Line Control tool (DFC.exe) must be in all workstations for the batch file to work.
If the Command Line Control was not copied to the workstations, then the steps to set workstations
into a Thawed state are very similar to those in the deployment process.
