Keyboard numlock state at startup

It is possible to configure whether Numlock should be enabled after logging in. The activation is controlled by setting this registry STRING value:

HKEY_CURRENT_USER \ Control Panel \ Keyboard\InitialKeyboardIndicators = "0"

"0" - All Keys off

"1" - Caps Lock on

"2" - Num Lock on

"4" - Scroll Lock on

For multiple keys, add their values:

"3" - Caps Lock and Num Lock on

"5" - Caps Lock and Scroll Lock on

"6" - Num Lock and Scroll Lock on

"7" - Caps Lock, Num Lock, and Scroll Lock on

Note it is also possible to configure Numlock state at startup before actually performing the login at the Welcome Screen, by setting the value for the default user:
HKEY_USERS \.Default \Control Panel \Keyboard\InitialKeyboardIndicators = "0"

Note if numlock is turned off before Windows has reached the login screen, then it might be caused by numlock not being activated in the motherboard BIOS.

Turn on network clients remotely

Wake on LAN (WOL, sometimes WoL) is an Ethernet computer networking standard that allows a shut-down computer to be turned on remotely. Most of new motherboards that has integrated ethernet controller supports this feature. You can enable the Wake on LAN feature in the Power Management section of the motherboard’s BIOS.

This is how Wake on LAN works. The target computer is shut down, with power reserved for the network card. The network card listens for a specific packet, called the “Magic Packet”. The listening computer receives this packet, checks it for the correct information, and then boots if the Magic Packet is valid. A magic packet is data consisting of “FF FF FF FF FF FF” followed by 16 repetitions of the listening network device’s MAC address.

There are many many Wake-On-LAN tools that can be downloaded on the Internet such as these below:

1. Nyxbull Wake on LAN [ Download Nyxbull Wake on LAN v1.0 ]

2. FUSION WakeUp on Lan [ Download Fusion WakeUp On LAN ]

WSUS Clients are not getting Updates

I'm seeing some indications that the SP1 installer, in some instances, removes the /selfupdate virtual directory from the Default Web Site.
So u have to create a virtual directory named 'selfupdate' with anonymous access enabled, and link it to the pathname at "C:\Program Files\Update Services\Selfupdate "
Check the folder permissions on the SelfUpdate directory, located at "C:\Program Files\Update Service\SelfUpdate", Make sure the IUSR_ComputerName has Read&Execute, Read, List Folders permission on the folder. (In some cases the IUSR_ComputerName permission is missing.)

Exchange 2007 POP3 Connector

If you want your internal users to receive email from others outside the LAN, there are 2 possible ways to do so.

1) Make a MX record on Internet dns servers that points to your mail server's public IP.

2) Let 3rd Party companies host your mail server. The problem is that in such a way you must have a POP3 account for each user. To solve this problem you can make a catch all account which receives all emails. Then your exchange server must connect to the hosting server and receive emails, after that your exchange server will decide the receiver and forward it to that mailbox. unfortunately exchange does not not support this so you must use some 3rd party software. You can find some of them here http://www.slipstick.com/exs/popconnect.asp

NOTE: A Catch-all for email, usually refers to a mailbox on a domain that will "catch all" of the emails addressed to the domain that do not exist in the mail server. Configuring a catch-all address can help avoid losing emails due to misspelling.

Transfer WSUS updates to another server

Step 1: Install WSUS on the new Server
Step 2: Match Advanced Options on the old WSUS Server & the new WSUS Server

1. In the WSUS console of the old WSUS server, click the Options tab, and
then click Advanced in the Update Files and Languages section.

console of the new server, click the Options tab, and then click Advanced in the
Update Files and Languages section.
4. In the Advanced Synchronization
Settings dialog box, make sure the settings for Download express installation
files and Languages options match the selections on the old server.

Step 3: Copy Updates from File System of the old WSUS Server to the new WSUS server

Backup WSUS updates at WSUSInstallationDrive:\WSUS\WSUSContent\ &
restore it to the new server WSUSInstallationDrive:\WSUS\WSUSContent\. ( U can
use ntbackup to do so)

Step 4: Copy Metadata from Database on the old WSUS Server to the new WSUS Server.

1. At the command prompt on the old Microsoft Windows Server Update Services
Server server, navigate to the folder that contains WSUSutil.exe.
2. Type the following:
wsusutil.exe export packagename logfile (wsusutil.exe export export.cab export.log)
3. Move the export package you just created to the new Microsoft Windows Server Update Services Server.
To import metadata to the database of the new Microsoft Windows Server Update Services Server.
Note:It can take from 3 to 4 hours for the database to validate
content that has just been imported. Please be patient.
1. At the command prompt on the new WSUS server, navigate to the directory that contains WSUSutil.exe.
2. Type the following:wsusutil.exe import packagename logfile (wsusutil.exe import export.cab import.log)

Clear credentials when conecting to a shared Folder

As you may know, the first time you enter your username/password to access a shared folder in a Window-based network, it remains in the system and Windows doesn't ask you for next attempts unless you reboot system. If u want to clear your credentials from PC without rebooting the machine U can type the following command in cmd:

Net Use * /d

U will be asked if u want to cancel your conection, So type Y.
