I found KB827664 at technet that has somewhat similar symptoms.
Basically you may need to reset the permissions in services?

Subject: an error 5 - (Access is denied)
NetOPS installed SP4 this weekend and now we are having problems with WIN2k
SQLServerAgent. I get following error when trying to stop or start the
Agent. Any comments would be greatly appreciated.
"an error 5 - (Access is denied) occurred while performing this service
operation on the SQLServerAgent service."
