XP Questions and Answers

Question

How can I use the registry to change the amount of disk space that Microsoft Internet Explorer (IE) uses to store temporary files in the Temporary Internet Files folder?

Answer

To change the amount of space that IE uses to store temporary Internet files, you typically open the IE Tools menu, select Internet Options, select the General tab, then click Settings under the "Temporary Internet files" section. However, you can also adjust this setting in the registry by performing the following steps:

1. Start a registry editor (e.g., regedit.exe).

2. Navigate to the HKEY_CURRENT_USER\Software\Microsoft\Windows\ CurrentVersion\Internet Settings\5.0\Cache\Content registry subkey.

3. Double-click CacheLimit, change the Base to Decimal, enter the amount of space you want to use for temporary Internet files (in kilobytes) in the "Value data" field, then click OK.

4. Navigate to the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion \Internet Settings\Cache\Content registry subkey.

5. Double-click CacheLimit, change the Base to Decimal, enter the same value you entered in Step 3, then click OK.

6. Close the registry editor.

The next time that IE starts, it will use the new size for the Temporary Internet Files folder.

Question

How can I configure Microsoft Internet Explorer (IE) to empty the Temporary Internet Files folder when I close the browser?

Answer

Temporary Internet files are essentially a log of everything you've viewed on the Web. To clear the Temporary Internet Files folder when you close the browser, perform the following steps:

1. Open the IE Tools menu, then select Internet Options.

2. Select the Advanced tab.

3. Scroll down to the Security section.

4. Select the "Empty Temporary Internet Files folder when browser is closed" check box, then click OK.

You can also use the registry to configure IE to empty the Temporary Internet Files folder upon exiting the browser by performing the following steps:

1. Start a registry editor (e.g., regedit.exe).

2. Navigate to the HKEY_CURRENT_USER\Software\Microsoft\Windows\ CurrentVersion\Internet Settings\Cache registry subkey.

3. Double-click Persistent, set its value to 0, then click OK.

4. Close the registry editor, then start IE for the change to take effect.

Remember that although you can configure IE to automatically empty the Temporary Internet Files folder each time you close the browser, your History log will still list the sites you've visited, so you might want to also manually clear this setting each time (go to the Tools menu, select Internet Options, select the General tab, then click Clear History).

Question

How can I prevent users from disabling the Remote Desktop Sharing settings in Microsoft Windows NetMeeting?

Answer

NetMeeting's Remote Desktop Sharing feature lets you gain control of another person's desktop, which is useful for Help desk personnel who need to see what's happening on a user's computer. However, users can easily turn off this feature. To prevent users from turning off Remote Desktop Sharing, perform the following steps:

1. Start a registry editor (e.g., regedit.exe).

2. Navigate to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Conferencing\ Mcpt registry subkey.

3. From the Edit menu, select New, String Value.

4. Enter the name Nx, then press Enter.

5. Double-click the new value, set it to 1, then click OK.

Users with typical access privileges will no longer be able to access the Remote Desktop Sharing option under the NetMeeting Tools menu. This setting doesn't affect an administrator's ability to turn off Remote Desktop Sharing.

Question

How can I print to a USB printer from the command prompt?

Answer

You typically print to a parallel-port printer by copying a file to the lpt1: device. Because USB devices don't connect through an LPT device, you can't take the same approach to print to a USB printer from the command prompt. However, you have several options that will work.

If a network adapter is connected to your network, you can share the printer with another machine on the network and map the printer to LPT2 or LPT3. For example,

net use LPT2 \<machine>\<printer> /yes

shares the printer on LPT2. By sharing the printer, you can copy files from the command prompt to the printer on that port.

If you don't have a network adapter, you can install the Microsoft loopback adapter, which emulates a network adapter, create a printer share on your machine, then use the Net Use command to print to the printer share.

Alternatively, if the USB printer is your machine's default printer, you can use Microsoft Notepad to print an ASCII file to the printer.

For example,

start /min notepad /P <filename>

prints the file from Notepad to the printer, where "filename" is the name of any file that you can open in Notepad that you want to print. You don't have to include "start /min" for this technique to work, but you'll want to include this command if you're printing from a batch file to minimize the command window while the batch file runs. Otherwise, the Notepad executable will steal focus away from the batch file that issues this command and could stall the batch file after printing is finished. To continue processing the batch file, you'd need to click the command window.

If none of the above techniques are suitable for your particular situation, check out the DOSPRN shareware utility available at http://www.dosprn.com . DOSPRN lets you print to any printer from the command line.

Question

How can I use Microsoft Internet Explorer (IE) to pass a username and password to an FTP site?

Answer

If you access an FTP site that doesn't allow anonymous access, you must provide a username and password. To access an FTP site anonymously from IE, use the syntax

ftp://ftp.<site name>.com

To pass a username and password, the syntax is

ftp://<username>:<password>@<ftp site>

For example, to access the Internet Software Consortium (ISC) ftp site, you might type

ftp://john:john@ibm.com@ftp.isc.org

where "john" is the username and "john@ibm.com" is the password.

Similarly, to pass just a username, you can use the syntax

ftp://<username>@<ftp site>

Question

I've upgraded or repaired my Windows XP installation, but now data is missing from the All Users folder. What caused this to happen, and how can I retrieve this information?

Answer

Data can disappear from the All Users folder if you've performed an in-place upgrade of XP (i.e., installed XP over an existing XP installation), used the XP installation CD-ROM and selected R to repair the XP installation, or upgraded XP Home Edition to XP Professional Edition. To recover the missing data, you must restore the information from a backup copy.

To prevent this problem from happening in the future, delete the undo_guimode.txt file. This file is typically in the \%windir%\system32 folder. The undo_guimode.txt file often appears on systems in which the manufacturer has preinstalled XP. The first time you start such a system, the system often calls a wizard that creates the file.

Question

What's the Google Toolbar 2.0?

Answer

Google has released an add-on for Microsoft Internet Explorer (IE) that provides fast access for performing Google searches and enhances your browser functionality. Some of the toolbar's features include

- blocking pop-up advertising

Question

Why does my PC keep rebooting with the message "This system is being shut down in 60 seconds by NT Authority/System due to an interrupted Remote Procedure Call (RPC)"?

Answer

The error you've encountered is a symptom of the MSBlaster (LoveSan) worm, which has been around since August 2003. To resolve this error, you first need to use the command

shutdown -a

to stop the system from shutting down so that you can patch the computer and remove the virus. Next, download and install the patch, which is available on Microsoft's Web site at

MSBlaster

To remove running versions of the virus from your PC, open Task Manager, select the Processes tab, then click End Process for all of the following processes:

- MSBLAST.EXE

- PENIS32.EXE

- TEEKIDS.EXE

- MSPATCH.EXE

- MSLAUGH.EXE

- ENBIEI.EXE

To prevent the virus from starting again, perform the following steps:

1. Start a registry editor (e.g., regedit.exe).

2. Navigate to the

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows \CurrentVersion\Run registry subkey.

3. Remove any value that mentions any of the executables listed above.

4. Close the registry editor.

5. Open Windows Explorer, search your Windows folder for any of the executables listed above, then remove those files.

6. If you're running Windows XP, enable the Internet Connection Firewall (ICF) and use Windows Update to keep your system up-to-date.

An automated virus-removal tool that replaces the steps above is available at W32.Blaster.Worm Removal Tool

(If you use this tool, you'll still need to download and install the patch from the Microsoft Web site.)
