The Holding Pattern: Lessons Learned on Litigation Holds « Bow Tie Law’s Blog

Ran across this post on the Bow Tie Law Blog talking about some items from the Napster case and Fawn Hall (you know, Ollie North) along with some of their own thoughts around litigation hold and litigation hold letters.

Very interesting read showing the need to have finely crafted and implemented policies and procedures.

Viewing mailbox sizes in Exchange 2007

As I was running a mailstorm against my Exchange 2007 virtual environment, I noticed that for some reason I had a few mailboxes that were missed in the random seeding that was happening.  I didn’t really care that these were missed, since I already had a system configuration of around 1500 mailboxes.  I mean really, who needs more for a test environment.

Anyway, I wanted to get rid of these non-populated mailboxes, but with 1500 mailboxes, I did not want to go through each and every mailbox within Exchange Management Console and hit properties to see if there was data contained in the selected mailbox.  Under Exchange 2003, Microsoft gave us a great pair of columns (Size and Total Items).  In Exchange 2007, Microsoft removed this and I have not seen nor heard any movement to bring it back.

In any case, I needed a way to get a list of the mailboxes showing me this information.  Fortunately, Exchange Management Shell provide a way to do this via the Powershell cmdlet Get-MailboxStatistics.  Here is what I ended up using to generate this and send to the screen.  I played a little with Export-CSV, but was not able to get the proper data in the file, so I left the sort with smallest mailboxes at the bottom.

Get-MailboxStatistics | Sort-Object TotalItemSize -Descending | ft DisplayName,@{label=”TotalItemSize(MB)”;expression={$_.TotalItemSize.Value.ToMB()}},ItemCount

This will output a list of all of mailboxes sorted by Item Size and Item Count (highest to lowest).  This makes it easy enough for me to get a list of my non-populated mailboxes to remove them from the system.  I have also used this to remove my larger mailboxes to free up some disk space in my test environment.

DDOS Attack Against Facebook, Twitter, Et Al. Was Because of One Guy's LiveJournal [DoS]

Check this post DDOS Attack Against Facebook, Twitter, Et Al. Was Because of One Guy's LiveJournal [DoS] from Gizmodo:

According to a Facebook executive, the target of today's DDOS attacks on Twitter, Facebook, LiveJournal, YouTube and other social media sites was one pro-Georgian blogger going by the username of "Cyxym." No word as to who was behind the attack.

 

Earlier today several competing social networks banded together to fight the DDOS attacks on their respective properties. Google and Facebook were able to keep the effects minimal while Twitter and others suffered periodic outages and severe slowness through out the day.

Max Kelly, chief security officer at Facebook, explained that the attack specifically targeted Cyxym, and was directed toward websites which he frequented or on which he held accounts, including his LiveJournal, where we find the first suggestion that there was a big target painted on his virtual back:

Cyxymu's LiveJournal page wasn't accessible, but a cached version showed that it was updated on Thursday with a message about the denial of service (DOS) attacks on his accounts on the US-based sites. "Now it's obvious it's a special attack against me and Georgians," the message in Russian said.

There is no word on exactly who was behind this attack and Kelly declined to speculate. But we wonder: Did Cyxym have a Gizmodo commenter account too or was the DDOS attack on Gawker Media an entirely unrelated coincidence? [CNET]


Windows 7 RTM available

The moment many of us geeky types have been waiting for.

Windows 7 RTM and its' many versions showed up TechNet Plus subscriptions today. Still waiting for Windows Server 2008 R2 to show up, but in any case, I will be grabbing this tonight and upgrading the home computer from the earlier build of Windows 7.
