The Pitfalls of MAC Filtering

Security is a top concern when it comes to 802.11 networking. Many are offering MAC filtering to protect small wireless networks but seems this one is not as secure as it is considered by some administrators:
"MAC filtering is the process of configuring an access point with a list of MAC addresses that will either be allowed or not allowed to gain access to the rest of the network via that WAP"

Finding Contacts in Public Folders with LookOut

Although it makes my outlook startup slow down but I needed a great search tool able to look up different contact folders in public folder at the same time instead of running the same query on every folder so I am using Lookout from Lookout Software again!

Jumping into 802.11 Networking

I am not writing very much anymore as I am involved in something new that makes me spend a lot of time studying and learning but this won't take long and I will start writing on regular basis in near future. Still Microsoft Exchange is part of the responsibility which makes me feel very satisfied in my new job. Past experiences and new learnings :)

Windows 2003 RRAS & VPN

I have set up my first VPN server on a windows 2003 RRAS today and it works fine as now. A great improvement to RRAS in Windows 2003 is its built-in basic firewall which blocks every traffic coming from the WAN connection including ICMP requests and exclusions can be defined easily on ICMP traffic, applications and services to let the traffic pass the firewall. Once a client is connected to the VPN server over internet it acts as if it has locally connected to the LAN drop and all resources are accessible normally. Outlook 2003 will download headers on slow connection to retrieve data from Microsoft Exchange on requests. I tried to connect to our servers from the Remote Desktops console and this also worked fine. The PPTP VPN connection is the only concern regarding security so I will work on it to make L2TP work for us.
