HOW TO STOP SPAM VIA WINDOWS MESSENGER SERVICE
Below you'll find many ways (sorted in the most successful ratio first) to stop the Windows Messenger service, depending on your system environment, some may require more than one process. This service is available only on NT, 2K, XP & Server 2003. Administrator Login is REQUIRED

About The Messenger Service


* Messenger is a Windows Service that runs in the background
* Messenger is not the same as MSN Messenger or any other Instant Messaging Program
* Messenger does not facilitate two-way chatting
* Many Windows Programs, Firewalls, UPS and Antiviruses require the Messenger Service
* Antivirus and UPS software, among others, may not work if Messenger is disabled
* The Messenger Service is usually turned on by default in most Windows NT, 2K and XP systems


1. Manually

1. Example 1

1. Click Start, Run and enter the following command:
RunDll32 advpack.dll,LaunchINFSection %windir%\inf\msmsgs.inf,BLC.Remove
NOTE: This will prevent a long delay when opening Outlook Express if you have the Contacts pane enabled
2. To prevent this, click Start, Run and enter {REGEDIT} Go to:
HKEY_LOCAL_MACHINE\Software\Mcft\Outlook Express
3. Right click in the right pane and select New, Dword value
4. Give it the name Hide Messenger Double click this new entry and set the value to 2
5. End result should look EXACTLY like this:
System Key: [HKEY_LOCAL_MACHINE\SOFTWARE\Mcft\Outlook Express]
Value Name: Hide Messenger
Data Type: REG_DWORD (DWORD Value)
Value Data: (2 = remove messenger)

2. Example 2

1. Copy and paste the following to Run Command Bar in the Start Menu:
RunDll32.exe advpack.dll,LaunchINFSection
%windir%\inf\msmsgs.inf,BLC.Remove

3. Example 3

1. If Example 5 didn't work, then try this - Many users miss or don't know of it
2. Click on Start then go to RUN and type:
C:\WINDOWS\inf\sysoc.inf
3. Change:
msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,hide,7
4. To:
msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,7
5. Then use Add/Remove Windows Components to remove Messenger
NOTE: You can also prevent access to Windows Messenger using Group Policy or the Set Program Access and Defaults utility added by default in Windows XP SP1 and Windows 2000 SP3

4. Example 4

1. Open Windows Messenger
2. From the menu, select "Tools" then "Options" then "Preferences" tab
3. Uncheck "Run this program when Windows starts"
4. Open Outlook Express
5. From the menu, select "Tools" then "Options" then "General" tab
6. Uncheck the option to "Automatically log on", if it's there
7. Also in Outlook Express, select "View" then "Layout"
8. Uncheck the option to "display Contacts" - The program will open a connection and display a list of all Contacts on line if you do not
9. In "Startup Folder" make sure there is no entry there for Messenger
10. Open Norton Anti-Virus if you have it installed
11. Click "Options" then "Instant Messenger"
12. Unckeck "Windows Messenger (recommended"
NOTE: This list ought to work in disassociate MSN from Outlook Express, so that it'll only start up if you really want it to

5. Example 5

1. 2000

* Click Start-> Settings-> Control Panel-> Administrative Tools->Services
* Scroll down and highlight "Messenger"
* Right-click the highlighted line and choose Properties
* Click the STOP button
* Select Disable in the Startup Type scroll bar
* Click OK

2. XP Home

* Click Start->Settings ->Control Panel
* Click Performance and Maintenance
* Click Administrative Tools
* Double click Services
* Scroll down and highlight "Messenger"
* Right-click the highlighted line and choose Properties
* Click the STOP button
* Select Disable in the Startup Type scroll bar
* Click OK

3. XP Professional

* Click Start->Settings ->Control Panel
* Click Administrative Tools
* Click Services
* Double click Services
* Scroll down and highlight "Messenger"
* Right-click the highlighted line and choose Properties.
* Click the STOP button.
* Select Disable in the Startup Type scroll bar
* Click OK

4. Windows NT

* Click Start ->Control Panel
* Double Click Administrative Tools
* Select Services-> Double-click on Messenger
* In the Messenger Properties window, select Stop
* Then choose Disable as the Startup Type
* Click OK
NOTE: If you stop the service and don’t adjust the startup type, the Messenger service will start automatically the next time you reboot. Keep in mind that when you disable the Messenger service, you'll no longer receive messages about an attached UPS, and you won’t be notified of print job completion, performance alerts, or antivirus activity (from Windows) not the program you're using for those purposes.

6. Example 6

1. To disable receipt of messenger pop-ups, verify that your firewall disables inbound traffic on UDP ports 135, 137, and 138, and TCP ports 135 and 139. On a system connected directly to the Internet, you should also disable inbound traffic on TCP port 445. If the system you want to protect is part of a Win2K-based network with Active Directory (AD), don't block incoming traffic on port 445 - Mcft Knowledge Base Article - 330904
Code:
http://support.Mcft.com/default.aspx?scid=kb;en-us;330904

NOTE: You can use the firewall approach only if your system doesn't communicate with legacy systems that rely on NetBIOS name resolution to locate machines and shared resources. If, for example, you let users running Windows 9x share your printer or scanner, when you disable inbound NetBIOS traffic, users won't be able to connect to these shared resources. Regardless of the method you choose, you can stop messenger spam

2. Program

1. Example 1

NOTE: On Oct 15, 2003, Mcft releases Critical Security Bulletin MS03-043 warning users that the Windows Messenger Service running and exposed by default in all versions of Windows NT, 2000 and XP, contains a "Remote Code Execution" vulnerability that allows any not otherwise secured and protected Windows machine to be taken over and remotely compromised over the Internet
1. Shoot the Messenger
Code:
http://grc.com/files/shootthemessenger.exe


2. Example 2

1. Messenger Disable
Code:
http://www.dougknox.com/xp/utils/MessengerDisable.zip

NOTE: If you choose to uninstall Windows Messenger on a system with SP1 installed, you will receive an error message about "un-registering" an OCX file. This is normal, and doest not affect the removal process. Windows Messenger will still be removed

3. TEST

1. Example 1

1. Right-click "My Computer"
2. Select "Manage"
3. Under "System Tools" right-click on "Shared Folders"
4. Choose "All Tasks" and select "Send Console Message..."
5. If you recieve the following error message then the service has been disabled, otherwise confirm that you have disabled it or try another example
"The following error occured while reading the list of sessions from Windows clients:
Error 2114: The Server service is not started."

2. Example 2

1. Click Start then "Run"
2. Type in {cmd.exe}
3. Type in net send 127.0.0.1 hi
4. If you get a popup "hi" message, then confirm that you have disabled it or try another example

4. IF YOU INSIST

1. If you insist on keeping Windows Messenger, then I'd recommend Messenger Manager - "Allows you to keep your messenger service running, as is intended and needed by Windows. This ensures that vital system errors and notifications may be sent informing you of Important System Events"
Code:
http://www.sellertools.com/default.asp?i=MessageManager3.htm

2. However, as a replacement to Windows Messenger remote control feature, I'd recommend this free tool Virtual Network Computing - "It is a remote control software which allows you to view and interact with one computer (the "server") using a simple program (the "viewer") on another computer anywhere on the Internet. The two computers don't even have to be the same type, so for example you can use VNC to view an office Linux machine on your Windows PC at home"

Data Capacity of CDs [Tutorial]

Data Capacity of CDs [Tutorial]

Abstract
You can fit on a S/VCD without overburning:
- approx. 735 MB of MPEG data onto a 74min/650MB disc
- approx. 795 MB of MPEG data onto an 80min/700MB disc

You can fit on a CD-ROM without overburning:
- approx. 650 MB of data onto a 74min/650MB disc
- approx. 703 MB of data onto an 80min/700MB disc

----------------------------------------------------------------

Introduction
Let us ignore for now the terms of megabyte for CD capacity and try to understand how the data is stored on a CD.

As well all know, the data is stored digitally as binary data. This means, however the actual information is actually kept on the disc, this information is in the form of "1"s and "0"s. Physically, the information on a CD is as pits on a thin sheet of metal (aluminium).

An a CD-R disc, the data is physically on an organic dye layer which simulates the metal layer on a real pressed CD.

----------------------------------------------------------------

How is the information structured
Now, on the CD, the information isn't just organised from beginning to end willy-nilly. Otherwise, it would be really hard to find a useful piece of information on the CD.

Rather, the information is organised in sectors. Consider a sector as like a page in a book. Just like you are able to quickly find something in a book if you know the page number, you can quickly find something on a CD if you know the sector number.

Now, remember that the CD was original made to hold audio data. It was decided, that the CD would would 75 sectors per second of audio. Although I cannot guess where this number comes from, it is quite appropriate for the audio CD. It means that you can "seek" an audio CD accurately to 1/75th of a second -- which is more than enough for consumer purposes.

Now, with this in mind, we can work out the total data capacity of user data for 1 sector.

----------------------------------------------------------------

The total data capacity of user data of 1 sector on a CD
CD audio uses uncompressed PCM stereo audio, 16-bit resolution sampled at 44.1 kHz.

Thus 1 second of audio contains:
16 bits/channel * 2 channels * 44100 samples/second * 1 second
= 1411200 bits
= 176400 bytes

Since there are 75 sectors per second
1 sector
= 176400 bytes / 75
= 2352 bytes

One sector on a CD contains 2352 bytes max.

----------------------------------------------------------------

The concept of different MODES and FORMS of burning
Now, audio CD was well and good, but the medium would become much more useful if you could store other data on the disc as well. This became to be know as CD-ROM of course.

Now, the audio-CD uses the ENTIRE sector for audio data.

However, for CD-ROMs this caused a problem. Simply, CDs and the CD reading mechanisms were not 100% faultless. That is, errors (indeed frequent errors) could be made during the reading. For audio CDs, this does not matter as much as you could simply interpolate from the adjacent audio samples. This will obviously NOT DO for data CDs. A single bit error could lead to a program being unexecutable or ruin an achive file.

Thus, for CD-ROMs, part of each sector is devoted to error correction codes and error detection codes. The CD-R FAQ has the details, but in effect, only 2048 bytes out of a total of 2352 bytes in each sector is available for user data on a data CD.

This burning mode is either MODE1 or MODE2 Form1.

----------------------------------------------------------------

MODE2 Form2 sectors of VCDs and SVCDs
Now, for VCDs and SVCDs, the video tracks do not necessarily require the robust error correction as normal data on a CD-ROM. However, there is still some overhead per sector that is used for something other than video data (e.g., sync headers).

S/VCDs video tracks are burnt in what is called MODE2 Form2 sectors. In this mode, only 2324 bytes out of a total of 2352 bytes in each sector is available for user data.

This is MUCH MORE than for CD-ROMs, but still less per sector than audio CD.

----------------------------------------------------------------

The disc capacities of CD-ROMs, audio-CDs and VCDs
Now, obviously what ultimately determines the capacity of a disc is the total number of sectors it contains. This is similar to the total number of pages in a blank exercise book (if you recall the book analogy).

The secondary determinant is the burning mode of the disc.

For audio CDs, it is as if you could fill each page from top to bottom with audio data as the entire sector is used for audio data.

For CD-ROMs, it is as if you need to first rule a margin and then leave the bottom part of each page for footnotes (headers + ECC + EDC). The amount of text you can actually write per page is then less due to these other constraints.

For S/VCDs, we still need to rule a margin on the page, but we don't have to worry about the footnotes (headers). We can fit MORE text than a CD-ROM, but less than an audio-CD.

Now remember, 1 second on a CD = 75 sectors.

Thus:
- 74 min CD = 333,000 sectors
- 80 min CD = 360,000 sectors


Data capacity in Mb for an audio-CD
74 min
= 333,000 sectors * 2352 bytes / sector
= 783216000 bytes
= 746.9 Mb

80 min
= 360,000 sectors * 2352 bytes / sector
= 846720000 bytes
= 807.5 Mb


Data capacity in Mb for a CD-ROM
74 min
= 333,000 sectors * 2048 bytes / sector
= 681984000 bytes
= 650.4 Mb

80 min
= 360,000 sectors * 2048 bytes / sector
= 737280000 bytes
= 703.1 Mb


Data capacity in Mb for a S/VCD
74 min
= 333,000 sectors * 2324 bytes / sector
= 773892000 bytes
= 738.0 Mb

80 min
= 360,000 sectors * 2324 bytes / sector
= 836640000 bytes
= 797.9 Mb

----------------------------------------------------------------

Conclusions
As you can see, the often quoted capacities of 650MB and 700MB refer to CD-ROM capacities.

Due to the fact that S/VCDs use a different burning mode where MORE of each sector is available as user data, the relatively capacities are HIGHER.

Now, since S/VCDs are not composed of PURELY video tracks and have some unavoidable overheads, the actually total capacity left for video tracks is a few Mb less for each disc (about 735 Mb for 74min discs and 795 Mb for 80min discs). This is where the often quoted capacities of 740MB and 800MB come from. They are quite accurate.

All these capacities are available BEFORE overburning. Overburning is where you burn MORE sectors than the disc is rated for. If you overburn, you can typically achieve about 1-2 minutes of additional capacity (depending on your drive and media).

Configuring ZoneAlarm Security Settings

 Configuring ZoneAlarm Security Settings
(

If you're running ZoneAlarm Pro you will probably have considered that most of the "advanced" settings might as well be in Chinese for all the use they are. User friendly they are not!

If you are not on a LAN (connected to another computer in a network) you can use this guide to give your firewall some real muscle and a new lease of life:

Launch ZoneAlarm Pro and click to highlight the "Firewall" tab on the left hand side . In the pane that appears on the right hand side in the section "Internet Zone Security" set the slider control to "High" Then click the "Custom" button in the same section.

The next settings page is divided into two sections with tabs Internet Zone and Trusted Zone at the top of the page. Under the Internet Zone tab there is a list of settings that can be accessed by scrolling. At the top is the high security settings and the only thing that should check from there is "allow broadcast/multicast". The rest should be unchecked.

Scroll down until you get to the medium security settings area. Check all the boxes in this section until you get to "Block Incomming UDP Ports". When you check that you will be asked to supply a list of ports, and in the field at the bottom of the page enter 1-65535

Then go back to the list and check the box alongside "Block Outgoing UDP Ports" and at the bottom of the page enter 1-19, 22-79, 82-7999, 8082-65535

Repeat this proceedure for the following settings
"Block Incomming TCP Ports": 1-65535
"Block Outgoing TCP Ports": 1-19, 22-79, 82-7999, 8082-65535
Then click "Apply", "Ok" at the bottom of the page.

Back in the right hand "Firewall" pane go next to the yellow "Trusted Zone Security" section and set it to "high" with the slider. Click "Custom" and repeat the above proceedure this time choosing the Trusted Zone tab at the top of the settings page.

These settings will stop all incoming packets @ports 1-65535 and also block all pings, trojans etc... this will also stop all spyware or applications from phoning home from your drive without your knowledge!

Computer Maintainance

You may not realize it, but your computer and your car have something in common: they both need regular maintenance. No, you don't need to change your computer's oil. But you should be updating your software, keeping your antivirus subscription up to date, and checking for spyware. Read on to learn what you can do to help improve your computer's security.


Getting started

Here are some basics maintenance tasks you can do today to start improving your computer's security. Be sure you make these part of your ongoing maintenance as well.

* Sign up for software update e-mail notices. Many software companies will send you e-mail whenever a software update is available. This is particularly important for your operating system (e.g., Microsoft VV!|VD0VV$® or Macintosh), your antivirus program, and your firewall.
* Register your software. If you still have registration forms for existing software, send them in. And be sure to register new software in the future. This is another way for the software manufacturer to alert you when new updates are available.
* Install software updates immediately.
When you get an update notice, download the update immediately and install it. (Remember, downloading and installing are two separate tasks.)
An ounce of prevention

A few simple steps will help you keep your files safe and clean.

* Step 1: Update your software
* Step 2: Backup your files
* Step 3: Use antivirus software and keep it updated
* Step 4: Change your passwords


Developing ongoing maintenance practices

Now that you've done some ground work, it's time to start moving into longer term maintenance tasks. These are all tasks that you should do today (or as soon as possible) to get started. But for best results, make these a part of a regular maintenance schedule. We recommend setting aside time each week to help keep your computer secure.

* Back up your files. Backing up your files simply means creating a copy of your computer files that you can use in the event the originals are lost. (Accidents can happen.) To learn more read our tips for backing up information.


* Scan your files with up to date antivirus software. Use your antivirus scan tool regularly to search for potential computer viruses and worms. Also, check your antivirus program's user manual to see if you can schedule an automatic scan of your computer. To learn more, read our tips for reducing your virus risk
.
* Change your passwords. Using the same password increases the odds that someone else will discover it. Change all of your passwords regularly (we recommend monthly) to reduce your risk. Also, choose your passwords carefully. To learn more, read our tips for creating stronger passwords
.

Making a schedule

One of the best ways to help protect your computer is to perform maintenance regularly. To help you keep track, we suggest making a regular "appointment" with your computer. Treat it like you would any other appointment. Record it in your datebook or online calendar, and if you cannot make it, reschedule. Remember, you are not only helping to improve your computer, you are also helping to protect your personal information.
