Symptoms
Assume that you use the multiserver environment in Microsoft SQL Server 2014 or 2016. When you try to enlist a target server to a master server by using the sp_msx_enlist stored procedure, if the length of the server name that you specified for the @msx_server_name argument is longer than 32 characters, the operation may fail. Additionally, you may receive an error message that resembles the following:
Note
Msg 22026, Level 16, State 1, Line LineNumber
The enlist operation failed (reason: The time-out was exceeded while the server waited for a response from SQL Server Agent. Make sure that the SQL Server Agent service is running)
