system error 5 has occurred access denied

I have windows 8, 32 bit & I'm trying to clear my print spooler, which I've done many times. I go to "run," type "cmd" & enter the command: "net stop spooler." When I execute the spooler command I get the above error message. I did a search on google & got a lot of hits but none of them were useful. What is going on & how do I solve this "system 5 error" problem?
Thanks for any help.
