Validating Connectivity With Windows Intune1. Download PSTools, see http://technet.microsoft.com/en-us/sysinternals/bb897553.aspx 2. Open an elevated admin CMD window 3. Change directory to the folder that contains PSexec (unless psexec is in a folder in your PATH already). Type the following line. (-i is for interactive, -s is to run as system) psexec -i -s cmd.exe hit ENTER 4. Another CMD opens after hitting “Enter” above. Verify you are now running as the system by typing whoami. The reply should be “nt authority\system” 5. Launch IExplore.exe and go to manage.microsoft.com. If the connection fails, the system account has been blocked. Hereby you can rule out Proxy/Firewall issue(s) here.
