2974003 - Error displayed when adding a system using logon group in the SAP GUI logon after changing the message server port number

Symptom

A system was already added in SAP GUI and the Message Server port number was changed later. User cannot logon to SAP system. If delete the system from SAP GUI and add again with message server IP address or hostname(without port number), it raises the message "Error: internal error (this retcode should be handled by caller of MS-layer)" or like the image below in SAP GUI.

Another symptom is add a system in the SAP GUI, select 'Group/Server Selection'. After input SID, message server IP address or hostname(without port number), no logon group can be selected in 'Group/Server' field and user cannot logon.
