Deleting a service permanently

Dear Friends,

I have a service called stinger running on my Win2kpro and I don?t know what is causing it to start and run every time I log on. I am able to stop it but I would like to know how can I find the files related to the services shown inwin2k pro task manager. Consider, for example, a service that is not a commom Win2k service and I am unable to guess where does it come from. How can I find the dll or other file linked to the service which is running in my task manager.

Thank you in advance,

Paulo
