Recently, I have been working in an Windows Server 2008 R2 AD environment that has a number of RODCs in branch offices. The environment uses DFSR (i.e. not FRS) for SYSVOL replication an I wondered whether I could simply remove the connection objects named “RODC Connection (FRS)”. To me, the use of “FRS” in… Read More »
I’ve been working with the Windows Server 2008 R2 Active Directory cmdlets quite a bit recently. If you’ve come from a background of using ADFIND, the cmdlets take a bit of getting used, but for me it’s definitely been worth the time spent.

The privileges assigned to these groups are obviously high and removing the members reduces the potential for costly mistakes and/or compromise. Here’s a quick Powershell snippet that will… Read More »
Many organisations choose to rename the Built-in Administrator account for the domain for security reasons. Whether or not renaming the account provides any real protection is the matter of some debate. What is clear is that any hacker worth his or her salt is not going to be fooled by the rename, because the account… Read More »
Here’s a little WMI script I threw together the other day to help someone out. The requirement was to set the display name (label) of a network adapter based on its hardware location. Let’s say we have a NIC with the display name “Local Area Connection” and you want to change it to “MyNIC”, but… Read More »
I’ve been running dual boot Windows 7 and Windows Server 2008 R2 on my laptop for a little while now. I use Windows 2008 R2 for running Hyper-V guests for testing and demo purposes. For some time I’d been running Microsoft Security Essentials on the Windows 7 partition, but without any Anti-Malware software on the… Read More »
I came across a problem the other day when using version 6.5.8211.0 of Microsoft Exchange MAPI and CDO 1.2.1 on a server running Good Mobile Messaging. The Good software accesses user mailboxes via the MAPI CDO client. At first the mailbox access was failing horribly with the following errors: 2011-03-11 13:24:33 12:00 ERROR:-2147219707 2011-03-11… Read More »
