\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\\SQL Server Agent\MsxEncryptChannelOptions matches in the master and the target servers. If not, modify the registries. This registry controls the encryption between the master and target server. The value 0 means no encryption. 1 means to encrypt without a certificate and 2 with a certificate.

The Force Defection button allows defecting the target server and the post-instruction allows posting the instructions.

SQL Server training EspañolHow to execute jobs on multiple SQL Servers
February 18, 2016 by Daniel CalbimonteIntroduction
In earlier chapter, we explained how to run queries in multiple SQL servers using the SQL Central Management Server. In this new chapter, we will show how to propagate a job from a SQL Server Master Agent Job to a target server. This feature is called Multiserver Administration. In a multiserver administration, you need a Master Server and one or more target servers. In the master server, you create a copy of the job and then it is copied and executed in the target servers. The jobs are scheduled to run and are executed in each Target Server.Requirements
SQL Server Installed (2 SQL Servers or 2 SQL Server Instances). 2 SQL Server Agents running.Getting started
Open the regedit, to edit the Windows registry and change the registry \HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\Figure 1. Registry In the SQL Server Management Studio go to the SQL Server Agent, right click and select the Multi Server Administration and select the Make this a Master option.

Some common problems
A very common problem when you are creating the target server (step 10) is the following message:Figure 19. Error Message when the target server is created. This error is related to the encryption between the master and target server. If you have this error, verify that the registry
\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\

Some administrative options
In the master server (MSX), it is posible to administer the Multi server configuration. Right click on the SQL Server Agent and in the Multi Server Administration, select Manage Target Servers.Figure 21. Multi Server Administration The target server status tab shows the list of target servers, the local time (the data and time of the target server in the local time) and the last time that the target server polled the master. The force poll button forces the poll of the selected target server to the master server. The Force Defection button allows defecting the target server and the post-instruction allows posting the instructions.

When the proxy is required
If a proxy is necessary, you will need to create a credential and then associate it with the proxy. Make sure that the proxy name is the same in the Master and Target servers.How to remove the target server
The option to remove the target server from the Multi-Server. You can do that on the target server. Go to the SQL Server Agent, right click and select Multi Server Administration>DefectFigure 24. Defect the Multi-Server system
Conclusion
As you can see, creating a master server and target servers is a straightforward process. Once configured, you can send jobs to multiple servers at the same time.
