Exmerge has a small bug

When you export items with exmerge to an pst file and you try to limit the mail items by setting the date, items from dumpster will always be exported.
Thats my rant of today.

How to make your windows network more secure using www.OpenDNS.org

Well this one is really simple.

On your windows 2003 server go to DNS right click the server go to your forwarders and add the opendns dns servers.
Also go to your root hints tab and remove those. (did you ever check if the default root hints are still valid nah I know, if you use em you should also update them)

Now for all your outgoing lookups the windows server queries the opendns servers.

Why is this safe?

Block the bad sites and whitelist the good.

Phishing Protection

We operate PhishTank.com, the world's most trusted source of phishing data. We integrate that data into an intelligence feed on our DNS servers to keep everyone on your network safe from phony sites trying to steal personal information.

Domain Blocking

You want to secure your network and have control over what resolves. We give you that control by providing the tools to block any website or DNS zone on the Internet, all through an easy-to-use interface.

Adult Site Blocking

Safeguard your kids, protect your students, or limit your corporate liability by blocking adult websites. Our adult site blocking solution can be deployed in minutes and provides granular levels of blocking. Hundreds of school districts are already using OpenDNS to achieve CIPA compliance. Did we mention it's completely free?

Web Proxy Blocking

Prevent people on your network from bypassing the access restrictions you put in place. Blocking Web proxies helps ensure your network remains secure.

Domain Whitelisting

We provide a (growing) list of Web content filtering categories to block, but sometimes there is a domain you want to make sure is never blocked, even if it's listed in a feed. Have the final say with our Domain Whitelisting feature.

Truecrypt 5.0 Released

Ok this is really a significant improvement!!!
I really love the pre-boot authentication.

download links below

New features:

  • Ability to encrypt a system partition/drive (i.e. a partition/drive where Windows is installed) with pre-boot authentication (anyone who wants to gain access and use the system, read and write files, etc., needs to enter the correct password each time before the system starts). For more information, see the chapter System Encryption in the documentation. (Windows Vista/XP/2003)
  • Pipelined operations increasing read/write speed by up to 100% (Windows)
  • Mac OS X version
  • Graphical user interface for the Linux version of TrueCrypt
  • XTS mode of operation, which was designed by Phillip Rogaway in 2003 and which was recently approved as the IEEE 1619 standard for cryptographic protection of data on block-oriented storage devices. XTS is faster and more secure than LRW mode (for more information on XTS mode, see the section Modes of Operation in the documentation).
    Note: New volumes created by this version of TrueCrypt can be encrypted only in XTS mode. However, volumes created by previous versions of TrueCrypt can still be mounted using this version of TrueCrypt.
  • SHA-512 hash algorithm (replacing SHA-1, which is no longer available when creating new volumes).
  • Note: To re-encrypt the header of an existing volume with a header key derived using HMAC-SHA-512 (PRF), select 'Volumes' > 'Set Header Key Derivation Algorithm'.
Improvements, bug fixes, and security enhancements:
  • The Linux version of TrueCrypt has been redesigned so that it will no longer be affected by changes to the Linux kernel (kernel upgrades/updates).
  • Many other minor improvements, bug fixes, and security enhancements. (Windows and Linux)
