Windows XP System Restore - worth a look
By Bryan Muehlberger

Microsoft Windows XP Professional and Home Edition offer a new feature
called System Restore that allows administrators to rollback recent
system changes to a Windows XP PC in order to recover from a recently
installed application that is causing problems to a system's stability.
It is also useful if an administrator wants to test a new application,
but still wants to be able to bring the system back to the state it was
in prior to the installation of the application. 

System Restore was originally intro

Windows 2000 Terminal Services - Modifying the listening port
By Bryan Muehlberger

Microsoft made the capabilities of Windows NT 4.0 Terminal Server
available as a service called "Terminal Services" with the introduction
of Windows 2000. 

Terminal Services enables you to deliver multi-user capabilities to
clients. It allows a Windows 2000 Server to maintain multiple
simultaneous sessions where all of the processing resources are managed
by the server, and only the screen updates are sent to the client,
giving the client the look and feel of a local Windows 2000 session.

Depending on your organization's needs, you can provide Terminal Server
capabilities by enabling the Terminal Services service on your Windows
2000 Server or Advanced Server installations.
 
By default, Windows 2000 Terminal Services uses TCP port 3389 for remote
desktop protocol (RDP). RDP is the protocol that the Terminal Service
uses to allow the client to connect to the Terminal Server. However,
most organizations like to control the default ports that different
services utilize within their networks.

By making a simple registry change, you can force the Terminal Services
service to start listening on a custom RDP port. Proceed at your own
risk, however. As with all registry modifications, I recommend only
experts familiar with the registry make this change, and only after a
backup of the registry is made. With the legal disclaimer out of the
way, let's show you how to implement the change.

To change the port used by the RDP, open up the registry editor
(REGEDT32.EXT) and navigate to the following key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal
Server\WinStations\RDP-Tcp

Find the "PortNumber" subkey and change the value from 00000D3D
(hexidecimal for 3389), to the port number that you desire. To find out
what the hexidecimal number is for the port you want to use, you can use
the Microsoft built-in calculator, or you can select decimal from within
the Registry Editor's modification box, type the number in decimal
format, and then select the hexidicimal button, which will convert it
back to hexidecimal for you. 

After completing the change, exit the Registry Editor. You must restart
the server for this change to take effect because the Terminal Server
service is part of the Windows 2000 kernel.  After rebooting, verify
that it is now listening on the new port by typing in the following
command in a command prompt window:

telnet yourserver.domain.com:newPortNumber

There is one caveat to making this change. You will only be able to take
advantage of this modifed port using the new RDP Client that comes with
Windows XP. The new RDP Client works on Windows 95, Windows 98 and 98
Second Edition, Windows Me, Windows NT 4.0 or Windows 2000.  Download
the software from
http://www.microsoft.com/windowsxp/pro/downloads/rdclientdl.asp.

After you install the new RDP Client, make a new connection by typing in
the server name followed by the new port number (i.e.
yourserver.domain.com:8080). If all works well, you will be able to make
the connection successfully. 

NOTE: If you are working behind a firewall, this will only work if you
configure your firewall to allow communications to this port.

 

duced in Windows Millennium Edition
(ME), but has been improved in the version released with Windows XP.
Using System Restore is simple, and Windows XP enables this feature by
default.
 
You launch System Restore by opening "Help and Support" on the Start
Menu, selecting "Performance and Maintenance" and then selecting the
"Using System Restore to undo changes".  Alternatively, you can type
c:\windows\system32\restore\rstrui.exe in the Run dialog window.

The System Restore wizard will walk you through the process of creating
a Restore Point, or restoring your system using a recent restore point.

You manage the System Restore settings through the System Restore tab
found in the System Properties Control Panel\System.

It is important to know that System Restore requires 200M-bytes of free
space on your hard disk, and by default, it will utilize 12% of your
drive's capacity for storing the restore points. The actual number of
restore points created by System Restore is calculated based on this
setting. In fact, 12% is the maximum percentage you are able to
configure through the graphical interface. 

All successful restorations are reversible and all failed restorations
are reversed automatically by the System Restore service.  In addition,
restore points are created automatically approximately every 24 hours or
when you install a new program, update windows, or create one manually
using the System Restore GUI (see Figure 1).

System Restore is a very useful utility that is worth taking the time to
learn and use.
