How
do I modify the Windows 2000
boot/system drive letter?
|
Microsoft doesn't recommend ever changing
the Win2K boot/system drive; however, if an automatic cause,
such as a mirror break, changes the drive, you can modify
the drive letter as follows (perform a full system
backup before you try this approach)—in this example, we
swap drives C and D:
-
Log on as an Administrator.
-
Start regedt32.exe.
-
Go to HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices.
-
Click MountedDevices.
-
On the Security menu, click Permissions.
Ensure that Administrators have full control (change
this setting back to its original value when you finish
these steps).
-
Quit regedt32, and start regedit.exe
(you MUST use regedit to perform the next steps).
-
Go to HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices.
-
Find the first drive letter you want
to change to a new drive letter. In this example, we
look for \DosDevices\C:.
-
Right-click \DosDevices\C:, and click
Rename.
-
Rename this value to an unused drive
letter (e.g., \DosDevices\Z:) to free up drive letter
C to use later.
-
Find the second drive letter you want
to change. In this example, we look for \DosDevices\D:.
-
Right-click \DosDevices\D:, and click
Rename.
-
Rename this value to the appropriate
new drive letter—in this example, \DosDevices\C:.
-
Right-click the value for \DosDevices\Z:,
click Rename, and name it \DosDevices\D:.
-
Quit regedit and, if you changed the
Administrators permissions setting, restart regedt32.
-
Change the Administrators permissions
setting back to the original setting.
-
Restart the computer.
Under
what conditions is Fast User
Switching available in Windows
XP?
|
Fast User Switching is an XP feature that
lets more than one user simultaneously log on, although
only one user account can be active at any time. For example,
say user John is currently logged on and Kevin needs to
print a document from his desktop. Without logging off
John, Kevin can log on, print his document, then make
John's user account active again without logging off to
perform the switch.
Several factors determine whether Fast User
Switching is available:
-
You must not be using a third-party
Microsoft Graphical Identification and Authentication
(msgina.dll) file.
-
The computer must not be a member
of a domain (this factor applies to XP Professional
only).
-
You must enable the Fast User Switching
feature (go to Start, Settings, Control Panel, User
Accounts, and select "Change the way users log on
or off"). If the computer has more than 64MB of RAM,
XP enables Fast User Switching by default.
-
The computer has sufficient free resources
to create an additional Winlogon service thread (when
multiple users are logged on, all the accounts--even
those note currently in use--use resources).
-
If your computer video card uses Shared
Video Memory (i.e., the computer uses a portion of
the system's RAM for video display memory), the shared
memory will minimize the amount of free RAM and can
cause XP to disable Fast User Switching.
Why
do I receive an error
when I attempt to run
the Windows .NET Server
(Win.NET Server) 2003
Administration Tools under
Windows XP?
|
Win.NET Server includes several updated
XP files, including dsprop.dll. The Administration Tools
require the Win.NET Server version of this file because
the base XP version doesn't contain necessary functions.
XP Service Pack 1 (SP1) contains the Win.NET Server version
of the file, so you must install XP SP1 before you attempt
to install the Win.NET Server Administration Tools under
XP. You can download the Administration Tools at Microsoft's
Web
site.
