Summary :
The SAP Note addresses issues where users are unable to connect to SAP systems via SAP GUI, manifesting errors like "Logon balancing error: could not connect to message server (rc=9)" and unknown service errors. This problem stems from an incorrect registry datatype modification (REG_EXP-AX to REG_SZ) triggered by MSN Messenger installations or the Connection Troubleshooter, inhibiting service directory resolution. The solution involves restoring the correct registry value datatype and expanding environment variables to ensure correct service paths in the database, with further measures recommended for affected systems including registry monitoring and log adjustments.
