Error when trying to login as technician other than "admin"

Error when trying to login as technician other than "admin"

I've added a couple Active Directory accounts as technicians ("super admins"). When I try to log in as any of them it redirects me to  http://<servername>:8888/j_security_check?loginComponent=AdminLogin&formSubmit=SSP and says "the webpage cannot be found"

If I try it from Chrome i get

Sorry,the page you requested was not found.
Please check the URL for proper spelling and capitalization. If you're having trouble locating a destination, try from our home page.

And when I click on "home" it just throws me back to the same message.
