I have already checed all the sql jobs and windows scheduled as well, there is no job scheduled .

about SQL DMO:

Most SQL Server administrative tasks are programmable by SQL-DMO, (DMO) is a set of programmable objects that come with SQL Server that make it easy to programmatically administer the databases instead of using the console we can do the following:

Scripting Objects

Backing up databases

Creating jobs

Altering tables and much more

As it is a COM object, you can use it in any COM friendly platform.

- the host name for DMO process is showing that database server name itself.
