Remote Assistance (RA)
A built-in service that enables another user,
typically a help-desk or IT employee, to
remotely help the end user with an issue
that she is experiencing on her Windows
XP computer.
Remote Desktop Connection
Client software that enables you to access a
Terminal Services session that is running on
a remote computer while you are sitting at
another computer in a different location.
This process is extremely useful for employ-
ees who want to work from home but need
to access their computers at work.
Remote Installation Services (RIS)
A server that provides Windows Server
2003, Windows XP Professional, and
Windows 2000 Professional operating-sys-
tem images that can be downloaded and
installed by network clients using network
adapters that comply with the preboot exe-
cution environment (PXE) boot ROM spec-
ifications. RIS requires Active Directory,
DHCP, and DNS to serve clients.
removable storage
Allows applications to access and share the
same media resources. This service is used
for managing removable media. Different
types of media include floppy disks, Zip
disks, CD-ROMs, CD-Rs, CD-RWs, DVD
media, and tape backup devices. Some
include removable hard drives as removable
storage.
Resultant Set of Policy
A summary of the group policies that are
imposed on a particular user or computer.
You can use tools such as Group Policy
Result, Group Policy Update, and the RSoP
snap-in to determine which policies are
being applied.
runas
A Windows XP GUI and command-line
tool that allows a user or an administrator
to run a program or to open a file under a
different user’s security credentials using the
appropriate user account name and pass-
word.
Safe Mode startup options
The options you get at startup when you
press the F8 function key to initiate Safe
Mode. When started in Safe Mode,
Windows XP uses only basic files and driv-
ers (mouse, monitor, keyboard, mass stor-
age, base video, and default system services
but no network connections) so Windows
can run and you can diagnose problems
with the system. You can choose the Safe
Mode with Networking option, which loads
all the preceding files and drivers plus the
essential services and drivers to start net-
working. Or you can choose the Safe Mode
with Command Prompt option, which is
exactly the same as Safe Mode except that
you get a command prompt instead of the
Windows GUI. You can also choose Last
Known Good Configuration, which starts
the computer by using the Registry infor-
mation that Windows XP saved at the last
shutdown. If a symptom does not reappear
when you start in Safe Mode, you can elimi-
nate the default settings and minimum
device drivers as possible causes. If a newly
added device or a changed driver is causing
problems, you can use Safe Mode to remove
the device or reverse the change. In some
circumstances, such as when Windows sys-
tem files required to start the system are
corrupted or damaged, the system will not
start in Safe Mode.
sampling interval or update interval
The frequency with which a performance
counter is logged. A shorter interval pro-
vides more detailed information but gener-
ates a larger log.
scheduled tasks
A system folder that stores scheduled jobs
which run at predefined times.
Administrators can create scheduled jobs.
Scheduled Tasks Wizard
A series of dialog boxes that simplify the
process of creating scheduled task jobs.
