You can actually manually download the file "WindowsPatchSupportedResources.cab" from the browser of the your SMP Server.
ITMS 8.7.1
As per KB "Detailed Import Patch Management for Windows access to SolutionSam and Vendor Download Sites" (KB 150321):
The Symantec Management Platform (SMP) Server uses Anonymous Authentication (IUSR) when calling the PMImport download and when downloading Software Bulletins from vendors to the SMP Server.
Note: If the Admin account is able to hit the URL in a browser; this shows that their account has permissions for their user credentials to access the SolutionSam site or URL for downloading the Software Update; this does not validate that the platform is able to access SolutionSam through your network. This only validates that the SolutionSam site is operational.
In this case, the intranet need to access internet via a proxy, hence need to configure the “Proxy” from the Notification Server Settings in Symantec Management Console
