Not too long ago, I wrote a network administration utility with specific needs.
One of the needs was to scan all the LAN pool for MAC addresses.
The code will look at your active network adapters, calculate start and end IP according to your address and netmask,
and query all the IPs within that range for their MAC address.
The code is written in C#, and it’s basically going over the whole range in a nested loop.
If you find this useful, you are welcome to use the code:

Recommended Software: Digsby
I’m the kind of guy who likes to be online. When I decide to be available for chat – the more the merrier.
Messenger, GTalk, GMail, Skype- you name it. 
I found about Digsby when I looked for a Facebook Chat client. Surfing the net brought me to Digsby’s website
and I must say I was impressed.
Digsby allows you to be online with all common IM clients all together as one contact list.
More than that – It also functions as email notifier and social network client (All of your facebook events for
example)
If you are “chat groupie” – I would really recommend you try this software
Last week, a friend of mine needed a solution that will auto-restart his PC at a specific time and run a specific task.
Normally, this wouldn’t be a big deal, but his problem was that the PC was inside a domain and required auto-login.
So I dug a bit inside the Windows registry and found a way to do that:
1. I backup all the registry keys in HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
2. I remove “legal notice” registry keys, to ensure that it won’t stop the PC from logging in by forcing to press Enter
3. Adding the username, password and domain as default registry keys, setting AdminLogon to True
4. Adding a shortcut in the Startup folder for my Post-Startup script
5. Restarting the PC
after the pc has been restarted, i delete all my added registry keys, and restore the backup. At my post-Restart script I also call the required script he wanted to run (in the attached example it is Windows Calculator)
This solution should only work on Windows 2000/XP Pro
All you need to do is edit postStartup.cmd to run your specific task, and schedule a run for preStartup.cmd with Windows Scheduled tasks (Start -> All Programs -> Accessories -> System Tools -> Scheduled Tasks)

PokeTalk – Call your friends for free
I recently came across this website www.poketalk.com.
This website allows you to place international phone calls for free!
What’s the catch? Well… a single phonecall is limited to 10 minutes, and you have 50 phonecalls per month (Tip- you can re-register with a different e-mail address to get extra 50 calls).
Once you place a call, the phone will ring at your house, and when you pick up, the phone will ring at the destination. That way both of you are having incoming calls and won’t be charged.
The main difference between this service and www.Jajah.com (another phone-to-phone service), is that you don’t have to register a specific number on either side to get the call for free.
So, this is definitely a website I recommend adding to your favorites.
