Vista - Permisisons error with services

I need to load two services to support a wireless air card. They are:
Remote Access Auto Connection Manager, and Telephony.
Apparently, they can both be loaded as "Local Computer", according to my wireless provider.

Questions:
--In Vista Business 32 bit, what causes an error 5: "Access denied", when you are logged on as Admin when trying to load a service?
--I get variously error 1079, and 1068 when trying to fool with the settings and load each of the two services above.

There are dependencies, I understand. Where can I go to figure out how to line everything up so these two will load?

Much thanks.
