How to restart the distributor agent of transactional replication? After troubleshooting query time out error I would like to restart my distributor agent.

So I go to my distributor server, in my distributor DB (called distribution_SA)  I run the following query:

select s.name as [servername],
       d.name,
       d.publication
      ,s.*
   --d.publication, d.local_job, d.publisher_db, d.job_id, s.name
  from distribution_SA.dbo.MSdistribution_agents d
      inner join master.sys.servers s on d.subscriber_id = s.server_id
 --where d.publication = @publisher
order by d.publication, s.name


this gives me the following result (I had to leave the server names on, apologies):
What I want to achieve is the list of jobs that I need to restart in order for the changes that I did on my distributor agent profile to take place.



The problem is that I haven't been able to find these jobs. Where are them? 

a) on the distributor

b) on the publisher

c) on the subscriber

Is there any better way of restarting the distributor agent?

I would prefer a T-SQL solution, when possible.
I found a simple solution here.

Distribution Agent - Start /Stop in T-SQL
-- To STOP the Distribution Agent:
sp_MSstopdistribution_agent @publisher, @publisher_db, @publication,
 @subscriber, @subscriber_db

--To START the Distribution Agent:
sp_MSstartdistribution_agent @publisher, @publisher_db, @publication,
 @subscriber, @subscriber_db


My complete implementation, working on my test environment is below.
I have left everything there, select queries and procedures, to remind myself, where to go to get the data to be used as parameters to the sp_MSstartdistribution_agent and sp_MSstopdistribution_agent stored procedures.
