Cleaning Up CSC Folders

C:\Windows\CSC folder is the offline files folder. It has special permissions. Without the correct permission, you won't be able to delete anything in it

To delete the content of C:\Windows\CSC, you need to modify its permissions

> cd c:\Windows
> takeown /f CSC /r /a /d y
> icacls CSC /grant Administrators:F

Then you can navigate to the folder and start deleting files

Publish TeamCity via Sophos XG Firewall

I am running TeamCity product at home for my development work and would like to publish the site via my Sophos XG Firewall. TeamCity runs on the internal domain namespace and to publish it to the Internet, you need to configure it so that it recognises the external domain namespace.

I don't want to make any change on the TeamCity, and luckily Sophos can do it !

Create Business Application Rule on your Sophos Firewall make sure the "Rewrite HTML" is selected as shown below. That's it!
