operating in a standby mode after completing the power-on self-test;

releasing the standby mode in response to receiving a release command from the main server;

performing booting of an operating system corresponding to a client, by communicating with the main server, after the release of the standby mode; and

performing booting of a pre-boot execution environment (PXE), by communicating with the main server, after performing the power-on self-test,

wherein the operating in the standby mode is performed after completing the performing booting of the PXE.

5. The method of claim 4 ,

wherein the performing of the booting of the PXE comprises:

loading a boot file of the PXE by receiving booting information from the main server, and

wherein the booting of the PXE is performed based on the loaded boot file.

6. The method of claim 4 ,

wherein the performing of the booting of the operating system comprises:

loading a boot file of the operating system by receiving booting information from the main server, and

wherein the booting of the operating system is performed based on the loaded boot file.

7. The method of claim 4 , further comprising:

providing a remote desktop service by communicating with the client through the network after completing the booting of the operating system.

8. A method of providing a remote desktop service with remote desktops to clients through a network, the method comprising:

commanding at least one remote desktop among remote desktops to power on, before receiving a service request for the remote desktop service from the clients; and

supporting booting of a pre-boot execution environment (PXE) of the at least one remote desktop;

operating the at least one remote desktop in the standby mode; and

commanding one remote desktop of the at least one remote desktop in standby mode to release the standby mode in response to receiving a service request for the remote desktop service from any one of the clients.

9. The method of claim 8 , further comprising:

monitoring a number of clients using the remote desktop service,

wherein the adjusting the number of the remote desktops having a standby mode comprises:

adjusting the number of the remote desktops having the standby mode, depending on a result of the monitoring of the number of clients using the remote desktop service.
