MSN common fault "step by step"

MSN this instant messaging tool is powerful and easy to operate, but the complex network environment will inevitably cause such problems, so that users can't figure out how to solve these problems. ? Let's take everyone into the MSN problem concentration area and answer questions.

MSN can't log in normally

The reason for this problem is more complicated. In addition to the user password error and improper setting of MSN itself, it is likely that the login is not normal for the following reasons:

1. Network problems

Today's networks are becoming larger and larger, and the environment is becoming more and more complex. Problems in one of the links may cause network failures, such as TCP/IP protocol components, network communication devices, network lines, Gateway server, etc. After the MSN cannot log in normally, you should use the Ping command to check whether the internal network is unobstructed. Then, use the Ping domain name (or public IP address) to check whether the public network is open. For direct access to the Internet. Users can use the "Ping domain name (or public IP)" command to view it.

2. MSN Server Issues

When Microsoft's MSN server fails or is maintained, it may also fail to log in properly. There will be corresponding prompts.

3. The network firewall is not properly configured.

When using MSN login, you need to use the TCP 3000 to 4000 port. If the client customizes the IP firewall IP rule and disables the TCP 3000 to 4000 port, the login will not work properly. Users are advised not to manually disable TCP ports 3000 to 4000.

4. Gateway Filtering Software Restrictions

In the LAN, the gateway filtering software can be used to disable MSN. Once disabled, users cannot log in to the MSN server. At this time, the user can use MSN to log in only by the administrator canceling the disable restriction.

Cancel MSN Auto Login

Click "Tools→Options" in the main MSN window, then switch to the "General" tab and cancel "Automatically log in to Messenger when I log in to Windows" Check the box and finally click the "OK" button.

In addition, in Windows XP you can use the "msconfig" command, click "Start → Run", enter "msconfig" in the run dialog box, switch to the "Startup" tab, cancel the "msmsgs" item Check the box and click "OK" to restart the system. This command is not available under Windows 2000 and can be copied from Windows XP.

Can't communicate voice and video

This is because the network firewall disables the port used by MSN voice, video and file transfer. It is easy for individual users or LAN users to encounter this problem. . For file transfer, the 6891~6900 ports of TCP are used, and the voice and video exchanges use UDP ports of 5004~65535. If you want to use them normally, you need to open the above ports.

The author takes Skynet firewall as an example to introduce how to open the above ports locally. In the "Custom IP Rules" window, click the "Add Rule" button to create a new "Open Voice and Video Port" rule. In the "Name" field of the rule, enter "Open Voice and Video Port" and "Packet Direction". "Receive or send", "Party IP address" is "any address", then switch to "UDP" in the protocol box, enter "5004" to "65535" in the port range, and then "when the above conditions are met" In the column, select "pass" and finally click "OK", which opens the ports required for voice and video communication.

The open file transfer port method is similar. The difference is that the file transfer port uses the TCP protocol. Be sure to pay attention when creating new IP rules. Select TCP in the protocol box, and then enter from "6891" to "6900". "Yes.

1601 Error Message

This message appears to be related to the corruption of the Windows Installer service. We must fix the Windows Installer service. View the status of the Windows Installer Service in the Service Management tool in Control Panel, which is generally disabled. When you try to enable this service, you will find that the service has been disabled by the system or the service has been marked for deletion. The following methods can be used to solve the problem.

●Windows 2000

First enter the "msiexec /unregserver" command in the command prompt window to stop the Windows Installer service, and then download the InstMsiW.exe installation package http://www.fyrose. Com/InstMsiW.exe), after decompressing, enter the directory, right click on the "msi.inf" file, select "Install", click the "mspatcha.inf" file in the same way, select "Install". Then enter the "msiexec /regserver" command in the command prompt window to start the Windows Installer service, and finally restart the Windows 2000 system.

●Windows XP

Windows XP has integrated Windows Installer v2.0, so there is no need to install it. First write a file using Notepad, the content is as follows:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Sevices\\MS IServer]

"ImagePath" =-

"ImagePath"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00, 6f,00,6f,00,\\74,00,25,00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32 , 00,5c00,6d\\0,73,00,69,00,65,00,78,00,65,00,63,00,2e,00,65,00,78,00,65,00, 20 ,00,2f,00,\\56,00,00,00

Then save the file as ".reg" format, double-click the file to import the contents of the file into the registry. Restart the computer to enter the safe mode (press F8 when starting), enter the "msiexec /regserver" command at the command prompt, and restart the system.
