Another problem that could be fixed with a script today. Moving machines and users to a different domain resulted in a problem for some people. Chrome is a very popular browser but a number of people have reported to support that Chrome takes a very long time to start and then open the first page after log in to windows.
It was determined that deleting the cache directory from within the users Chrome application data folder resolved this.
Waiting for every effected user to report the problem wouldn’t be a great course of action of course. It would be a lot better to proactively go after all Chrome installations and remove the cache directory.
So that’s what I’ve done. The script does the following:
- Check to see if the computer is on the network by pinging it.
- List all the user directories in c:\users on each computer.
- Check to see if the Chrome cache directory exists.
- Deletes the cache directory.
- Logs the result including any encountered errors to a file called results.txt.
I could have searched Active Directory directly of course but I want to be able to easily add and remove computers when needed. It also allows me to run the script on 10 computers to start off and ramp up to a few thousand by the end.
It should go without saying that as the script uses the admin share, you need to have access to the workstations that you intend to administer.
