We can use sc.exe in the Windows Server 2003 to control services, create services and delete services.
Since some people thought they must directly modify the registry to delete a service, I would like to share how to use sc.exe to create or delete a service without directly modifying the registry so that decreased the possibility for system failures.

To create a service:

Click “start“ – “run“, and then enter “cmd“ to open Microsoft Command Console.

Enter command:

sc servername create servicename

 

To delete a service:

Click “start“ – “run“, and then enter “cmd“ to open Microsoft Command Console.

Enter command:

sc servername delete servicename

 

For instance, sc \\dc delete myservice

(Note: In this example, dc is my Domain Controller Server name, which is not the local machine, myservice is the name of the service I want to delete on the DC server.)

 

Below is the official help of all sc functions:

QUERY and QUERYEX OPTIONS:

If the query command is followed by a service name, the status for that service is returned. Further options do not apply in this case. If the query command is followed by nothing or one of the options listed below, the services are enumerated.

type= Type of services to enumerate (driver, service, all) (default = service)
state= State of services to enumerate (inactive, all) (default = active)
bufsize= The size (in bytes) of the enumeration buffer (default = 4096)
ri= The resume index number at which to begin the enumeration (default = 0)
group= Service group to enumerate (default = all groups)

SYNTAX EXAMPLES
sc query – Enumerates status for active services & drivers
sc query eventlog – Displays status for the eventlog service
sc queryex eventlog – Displays extended status for the eventlog service
sc query type= driver – Enumerates only active drivers
sc query type= service – Enumerates only Win32 services
sc query state= all – Enumerates all services & drivers
sc query bufsize= 50 – Enumerates with a 50 byte buffer
sc query ri= 14 – Enumerates with resume index = 14
sc queryex group= “” – Enumerates active services not in a group
sc query type= interact – Enumerates all interactive services
sc query type= driver group= NDIS – Enumerates all NDIS drivers
