Domain Controller Upgrade

We finally started upgrading the domain controllers (DCs) here at Translink, which are currently running Windows Server 2003, to Windows Server 2008 R2. Yay! As I told you in a previous post, this is necessary for the Exchange 2010 migration to start.

On Thursday after lunch Rory, a server technician working for Northgate, came to our office to support us with the migration.

First we set up a temporary (virtual) DC, moved the services and copied the FSMO roles to it.

Now we could start upgrading the DCs. As Windows Server 2008 R2 doesn’t allow an in-place upgrade from Windows Server 2003, we had to do a complete new installation. So we demoted the first DC to a normal member server and then removed it from the domain. Now we could install the new operating system, get a cup of tea, do some basic configurations, join the freshly installed server to the domain and run dcpromo to make it a DC again. Of course we repeated this procedure for all DCs, one at a time.

Finally we moved the FSMO roles back to the DCs they were initially running on, moved the services … and Bob’s your uncle! 😉

In the end we left the office at approximately 19:30.

Active Directory Upgrade

This week I was introduced to another project at Translink: Plans are to upgrade the Active Directory infrastructure from Windows Server 2003 to Windows Server 2008 R2. The project is realized in cooperation with the IT service provider Northgate.

One principal reason for running this project is that another project depends on this Active Directory upgrade: the migration from Exchange 2003 to Exchange 2010.

A project assistant from Northgate came to the office to talk with my colleagues and me about the hardware (physical and virtual) and software requirements as well as the necessary network (re)structuring.

Cisco Heaven

Yesterday my work day started with a visit at Translink’s „data center“ at Belfast Central Station.

They have servers …

… networking equipment …

switches and cables

… and when it comes to structured cabling Translink strives for perfection! 😉

As you can see it’s rather a storeroom with a rack, some switches and an air conditioning system put in than a real data center.

I went there with my colleagues John and John, who both do most of the networking stuff at Translink. Why did we go there? The IS department just got a new redundant SAN system and plans are to move one part to Central Station to improve redundancy. To prepare this we met a network technician from Northgate (an IT service provider supporting Translink’s networking staff). He was introduced to Translink’s core network infrastructure with multiple sites connected via fibres and copper wires. After that he rushed through the core switch consoles, reviewed the configurations and presented some things that need to be changed in order to make the SAN replication work. We will get a full report soon.

The whole Translink data network is built on Cisco technology (as far as I know) so I hope there will be several opportunities to utilize my networking skills earned in the CCNA course in this (and coming) project(s).
