1- Open up the Maintenance Plan designer in LiteSpeed
2- Click on the Manage Connections toolbar option - the button is to the far right
3- Edit the connection and change as needed
Workaround:
LiteSpeed Console does not have the function to change the owner of the maintenance plan. The only way to do this, is change it manually.
Steps to change the owner of a maintenance plan (MP):
First use the query
Select * from MSDB..Sysusers
to get ownerid.
2005
UPDATE
[msdb].[dbo].[sysdtspackages90]
SET
[ownersid] = <ownerid>
WHERE
[name] = <maintenance plan name>
2008
UPDATE [msdb].[dbo].[sysssispackages]
SET
[ownersid] = <ownerid>
WHERE
[name] = <maintenance plan name>
To change the owner a job:
UPDATE [msdb].[dbo].[sysjobs]
SET
[owner_sid] = <ownerid>
WHERE
[name] = <job name>
