Below, let us feel a little command, in the maintenance of network security Power!

1, refused to start the unknown service

How did it happen that the server suddenly became "unresponsive" one day? This phenomenon, mostly illegal attackers through the intrusion server system in the server to enable a special network services, if not stopped in time, server system resources will soon be exhausted.

In fact, with the "net start" command built into the Windows Server system, you can clearly understand what services the current system is opening and prohibit the routing of unknown services in a timely manner. The screen will be switched to MS-DOS after you open the system's Run dialog box, and then enter the cmd command, and then click Enter. At the DOS command line, you can execute the net start command directly, and then the system will automatically list the services that are currently started (as shown in Figure 1), examine carefully what services are of dubious origin, and then execute the "net stop server" on the command line Command (where server is a specific unknown service), temporarily stop the unknown service.


2, forced to specify the password policy

To prevent the login server's account from being "stolen" by other outlaws, you can use the "net accounts" command to force the login user to change bad password usage habits. For example, a "forced" password must have a minimum number of digits, forcing the user to change the password on a regular basis.

For example, the server logon user to create Access account password when the number of digits not less than 6 digits, you can directly in the DOS command line input "Net accounts/minpwlen:6" command, click Enter, the new account password number will be "forced" not less than 6 digits.

If you want to "force" the user to modify the password in a specified time, you can execute the following command "Net Accounts/minpwage:n" (where n is the specific number of days); For example, require users to modify passwords every 6 days, as long as the implementation of the "net Accounts/ Minpwage:6 "on it. If you want to specify that the user must modify the password within a certain time period, you can execute the "Net accounts/minpwage:n1/maxpwage:n2" command, where "N1" is the minimum number of days, "N2" for the maximum number of days.
