  • Blog Post: Log-Event

    mitchk2
    Recently I had a need to write to the event logs using PowerShell. I knew there was a built in command for this action so I decided to test it out. After some time using the Write-EventLog cmdlet, I kept getting errors generated which seemed to be symptoms from the following constraints of the event...

  • Blog Post: Shutting Down an Exchange Site

    mitchk2
    The argument could be made that this script is not something that has a practical use. One of my customers had a requirement to quickly (and gracefully) shut down an entire site of Exchange servers. I assume the scenario would be due to some kind of natural disaster or cooling issue in a datacenter....

    This month’s post will be a short one – and there’s not much code to this topic, it’s just an observation. When I write scripts, I like the idea of adding some output to track what my script is doing, especially if there’s an issue with the script. It’s so much easier to find bugs or performance issues...

  • Blog Post: Estimating/Calculating Execution Time

    mitchk2
    Over the years, I’ve noticed that I develop a general routine depending on the needs of my current customer. When I get to work in the morning I generally check a few items that I know can develop into hot button issues. As a general rule, if I am going to repeat a task more than a few times, I...

  • Blog Post: Collecting Mailbox Counts per Database Using LDAP

    mitchk2
    Recently I have been gathering a lot of mailbox data for a customer running Exchange 2010 that is in the process of upgrading from Exchange 2007. One of the more frequent requests has been for mailbox numbers, often broken out by database. It’s key to know the current state of your environment...
