Hi,
Thank you for posting in Microsoft Q&A forum.
1,Any errors in SMSAdminUI.log under \Program Files\Microsoft Configuration Manager\AdminConsole\AdminUILog? The user account that you are using, check if it is added as Administrative User from console:
Check Administration->Security->Administrative Users and make it a member of the required security role.
Note: It should have the Site Read permission included.
2,For a test turn off the firewall, does it work? Have you also tried to simply restart SQL and smsexec?
Thanks for your time. Have a nice day!
Best regards,
Simon
