Backup, Backup, Backup your data. Then go back and verify those backups. Then do test restores. Some administrators may say this is being paranoid. Thinking that looking at the logs and verifying everything has a "green checkmark" by it is good enough is arrogant. I once had an issue where for 4 months a set of our backups were failing going to tape. The software showed that everything backed up successfully, but we found there was some known issue with our tape library that was causing an issue. Luckily we had no major catastrophic event where we needed it, but it changed my way of thinking on how to manage backups.
See a video below of how Pixar had a similar issue.

Hyper-V CSV Possible Owners
So this past weekend we had an issue with Windows disconnecting our CSV's during a routine backup of the Virtual Machines. We were able to reconnect the storage once we removed some SCSI reservations. Once we had the storage up we tested failover and one CSV was fine, the other CSV wouldn't failover to a particular host. Through digging we found out that somehow the node having the issue was not assigned as a possible owner for the disk. Unfortunately, with CSV's you can't do this through the GUI, it has to be done via the command line. To the issue open the command prompt (with elevated privileges) and run the following command. Replace "MyCSV" with the name of your CSV, and replace nodename with the name of the node that needs to be added to the list of possible owners.
cluster res “MyCSV″ /ADDOWNER:nodename

Monitoring Lync (My Ignorant Method)
So I'm going to preface this blog entry with saying that, I have had no Lync training what-so-ever. Everything I know is self taught. So needless to say, I'm ignorant on the matter.
So the firm I work for has been testing out video conferencing solutions. Everything from Webex, to GoToMeeting. I one day suggested to my boss that we give Lync a shot. He said give it a shot. So I provisioned a 2008 R2 VM, and installed Lync. I got it running in the most basic form. IT has been playing with it, and we love it. The partner's loved it because the base product was already included in our EA agreement.
It was decided to push Lync out to all the Attorneys to let them get a feel for the product by itself, and do some video conferencing with other attorneys in different offices. Unfortunately, I will not have full Lync training until the end of April. So one of things I needed to do was to find who was actually using the product. So I rounded up the below script. It counts the total items of the Conversation History folder, and sorts it from largest to smallest. Then it puts the results into a CSV. You will need to run this from the Exchange Powershell.
