The Microsoft Support Diagnostic Tool: Restrict tool download machine setting should be configured correctly. Restricts the tool download policy for Microsoft Support Diagnostic Tool. Microsoft Support Diagnostic Tool (MSDT) gathers diagnostic data for analysis by support professionals. For some problems, MSDT may prompt the user to download additional tools for troubleshooting. These tools are required to completely troubleshoot the problem. If tool download is restricted, it may not be possible to find the root cause of the problem. If you enable this policy setting for remote troubleshooting, MSDT will prompt the user to download additional tools to diagnose problems on remote computers only. If the setting is enabled for local and remote troubleshooting, MSDT will always prompt for additional tool download. If you disable this policy, MSDT will never download tools, and will be unable to diagnose problems on remote computers. If you do not configure this policy setting, MSDT will prompt the user before downloading any additional tools.
