If On-Box Sandboxing is not active on CAS S400 and S500
When you enable on-box sandboxing, you have the option of immediately downloading the Windows base image so that you can set up a virtualized Windows environment for sandboxing.
Depending on your network, the download process could take a while, so make sure you have sufficient time before beginning.
Enable your On-box Sandboxing license.
Select the On-box Sandboxing check box.
Click Save Changes. A Confirmation dialog asks if you want to create a Windows profile.
If you have time to download the Windows base image now, click Yes. Due to the size of this file, downloading can take quite some time. To perform this task later, click No and then refer to Add Windows Base Image.
Enter the Microsoft Windows Product Key. The product key is located on the Windows license documentation you received after purchasing the on-box sandboxing license. You may type the key in upper- or lowercase, but you must include the dashes.
To use a 30-day trial license, select Use Trial Key. (See Convert from Trial to Full Windows License for On-box Sandboxing - check this article )
Since the base image is a large file, it will take quite some time to add to Content Analysis, even if it's downloading from the local network.
If the base image failed to load or Windows didn't activate, the Status column will display a descriptive error message; see Troubleshooting Windows Image Download Issues.
In the Servers panel, make sure Local Instance is enabled.
Save any changes you may have made.
