make Test run last in a Nunit test project

from what i could find till now , i am not sure it is possible , but maybe there is something that i am missing.

like in any test project we have lots of tests classes ( in our case these are E2E tests that runs on an live system)

when in some tests we need to run a script as a prerequisite that triggers an iis reset command .

which affect other tests ..

so what we want achieve is running these tests ( tests that triggers iisrest one by one ) after all other tests where executed.

thanks
