Hello @Babs-9473
1). check your NIC bindings and put IPv4 first above IPv6.
2). ensure the IP of the Essentials server is the ONLY DNS entry on the workstation.
3). check event log entries, the log files for the connect computer process is located in a hidden file on the C drive.
Also please refer to this article for troubleshoot: Troubleshoot connecting computers to the server in Windows Server Essentials
Best Regards
Karlie
