13.2 Stopping and Starting the DNS Server Service
There are a couple of options
for stopping and starting the DNS server on Windows Server 2003. The
net stop and
net start commands have been around since the
early days of Windows NT and are commonly used to stop and start
services, if for no other reason than their availability and
simplicity. You specify the name of the service after the command to
stop or start it. Here is an example of
restarting
the DNS server in two steps using these commands:
C:\> net stop dns
The DNS Server service is stopping.
The DNS Server service was stopped successfully.
C:\> net start dns
The DNS Server service is starting.
The DNS Server service was started successfully.
While these commands are certainly easy to use, they
don't work on a remote server. If you need to stop,
start, or restart the DNS server on a remote server,
you'll need to use the
sc utility.In Windows 2000, the sc utility
was available in the Resource Kit. In Windows Server 2003,
it's installed with the operating system, like the
syscomgr and
net commands we described earlier.Not only can sc be run against
remote servers, but it provides options to perform just about any
action you would need to do against a service. To restart the DNS
server on a remote server named
matrix, we would use the following commands:
C:\> sc \\matrix stop dns
SERVICE_NAME: dns
TYPE : 10 WIN32_OWN_PROCESS
STATE : 3 STOP_PENDING
(STOPPABLE, PAUSABLE, ACCEPTS_SHUTDOWN)
WIN32_EXIT_CODE : 0 (0x0)
SERVICE_EXIT_CODE : 0 (0x0)
CHECKPOINT : 0x1
WAIT_HINT : 0x7530
C:\> sc \\matrix start dns
SERVICE_NAME: dns
TYPE : 10 WIN32_OWN_PROCESS
STATE : 2 START_PENDING
(NOT_STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN))
WIN32_EXIT_CODE : 0 (0x0)
SERVICE_EXIT_CODE : 0 (0x0)
CHECKPOINT : 0x0
WAIT_HINT : 0x7d0
PID : 504
FLAGS :
As you can see, the second command returned a START_PENDING state. To
verify the service started successfully, we can use the
query option:
C:\> sc \\matrix query dns
SERVICE_NAME: dns
TYPE : 10 WIN32_OWN_PROCESS
STATE : 4 RUNNING
(STOPPABLE, PAUSABLE, ACCEPTS_SHUTDOWN)
WIN32_EXIT_CODE : 0 (0x0)
SERVICE_EXIT_CODE : 0 (0x0)
CHECKPOINT : 0x0
WAIT_HINT : 0x0
We recommend using sc instead of
the net command. In its most
basic form, sc is just as simple
but much more powerful. The following help entry lists all the
options supported by sc:
DESCRIPTION:
SC is a command line program used for communicating with the
Service Control Manager and services.
USAGE:
sc <server> [command] [service name] <option1> <option2> . . .
The option <server> has the form "\\ServerName"
Further help on commands can be obtained by typing: "sc [command]"
