Dcpromo Error: No Other Active Directory Controllers?
KB ID 0001453 Problem I was trying to demote a domain controller yesterday morning, it was a 2008 R2 Domain controller, (in fact it was SBS 2011). I’d already added a nice new Server 2016 Domain Controller to the domain, and transferred all the FSMO roles, so I was surprised when I tried to gracefully demote the old DC and got this; You did not indicate that this Active Directory domain controller is the last domain controller...
WannaCry – Protect Yourself
KB ID 0001311 Dtd 15/05/17 Problem Last Friday, the IT world was hit by another attack, WannaCry is a Ransomware infection, that exploits a hole in the windows SMB Protocol. This hole was patched back in March, (Security update MS17-010) so if your, (windows update supported systems) have updates enabled, you will probably already be protected. Why were big organisations like the NHS hit? Primarily because they have systems that are...
ADMT (Active Directory Migration Tool) Domain Migration – Part 2
KB ID 0001306 Dtd 06/05/17 Problem Back in Part One we setup our migration admin account, and installed ADMT.

Robocopy – File Server Migration
KB ID 0001233 Dtd 25/08/16 Problem I’ve done a lot of migrations, and moving a client’s files and shared data, usually makes them cringe. I’ve lost count of the amount of times I’ve heard ‘We can’t have any downtime’, which is fine, until you tell them how much its going to cost to do this on a Saturday! As I posted recently, Microsoft have made this a lot easier with the file serve...
IIS – Cannot Download File From Website (With Extension .xyz)
KB ID 0001223 Dtd 02/08/16 Problem I first saw this problem a few months ago, when I wasted to download some .bin and .pkg files from a web server running IIS, into a Cisco firewall. Then again this week I needed to get a large .iso file into a clients network so I put it on a publicly accessible web server running IIS, and had the problem again. Solution On the IIS server, open administrative tools > Internet Information...
Windows Server – Migrating Files / Folders / Shares / User Profiles
KB ID 0001201 Dtd 04/06/16ProblemWhy isn’t this better publicised? Did you know Microsoft have a set of Migration tools, and one of them is for file servers? Now traditionally I’d use RoboCopy or XCopy to migrate files and folders, and for ‘User Profiles’ I would normally back them up, and restore them to the new server. This is because the file permissions on ‘correctly deployed’ user profiles mean...
