It seems that a couple of weeks ago my standalone Exchange Online Protection (EOP) configuration was changed without me being involved. Basically, it looks like my default Accepted Domain was changed from type “Internal Relay” to “Authoritative” without my knowledge or consent. The first I knew of this was when I noticed my on-premises mail… Read More »
The default location for newly provisioned user and computer objects are (respectively) the Users and Computers containers. Since Windows Server 2003 Active Directory the option has been available to redirect these to OUs that you specificy. Why would you want to do this?

There are well known methods for setting Access Control Entries (ACEs) on Active Directory objects using Powershell. One example is the following: http://blogs.msdn.com/b/adpowershell/archive/2009/10/13/add-object-specific-aces-using-active-directory-powershell.aspx The method relies on you knowing the schemaIDGUID of the schema object classes you are working with (e.g. User, Computer, Group).

Another quick one to finish the year off. Here’s a script that runs an LDAP query against all of the DCs in the forest and reports back the time it has taken for each. The intention is to identify any DCs that are responding slowly for some reason. In the example below, I’ve chosen to… Read More »
I came across a weird error the other day while running Exchange Server 2013 CU6 setup with the /PrepareAD switch. The error (from the Exchange setup logs) was this: [12/02/2014 01:14:16.0727] [2] [ERROR] Could not find the Exchange Mailbox Administrators Universal Security Group through its well-known GUID 29a962c2-91d6-4ab7-9e06-8728f8f842ea.

Had a weird one earlier today. I installed the Windows Server Backup feature on two Windows Server 2012 R2 servers in the same VMware farm. On one server I could start the wbadmin.msc snap-in immediately, but on the other I couldn’t find it at all. I couldn’t find anything in the event logs to explain… Read More »
The first thing that struck me after lifting the phone out of the box was how heavy it was. My Samsung S3 (the sole victim of a fatal hit-and-run incident recently) was much lighter.
