start jobs

Hi,
There are several windows apps, services, sql jobs that I have created. These run automatically each day at different times.

I have created an asp.net intranet for the company.
I would like to have a page which will allow the above jobs to run if they fail.
How can I start these jobs from a .aspx page.

For example I would like to click a button or a hyperlink which will then start a job which is written in windows in vb.net or c# or a job which is a sql server job.
Hope this is clear.
Thanks guys...
