Apply a template to a category archive

Hi Guys,
I am trying to apply a template so that when I view the category archives the template is applied to the archives of that category. I have not had any success in achieving this and I could not find information on this. I have been able to apply templates to almost any scenario except the category archives.

Any assistance would be appreciated

Bit late, but for those who arrive here.
Template->Archive->Categories and Tags->All Terms
