In server core server (Windows 2008 with only command prompt) you cannot view the list of services. In other words, services.msc is not available.
We have to use the ‘net’ command for starting or stopping services.
Here to there is a problem. you cannot start a service with its name. You have to use “shortname”
For example, to stop “Altiris monitor agent” service we have to type as net stop metricprovider.
To know the “shortname” of a service, on a normal identical server, open services.msc -> Right click the particular service -> Properties -> General -> Service name.
