Wifi, iTunes and Airport

I’ve been playing music via iTunes to my Apple Airport for a while – and it’s always been pretty perfect.

Recently however the music keeps stopping and starting – nothing seemed to fix it.

Then I found a firmware update for the Airport – here – that seemed to work. I moved the wifi to use channel 11; updated the Airport and everything is now happy.

Hey you in Sandvika

I use Google Analytics to track traffic to this blog. I commented on this earlier – and sorry for the almost 30k payload!

I noticed tonight a visitor from the far north of Norway – in Sandvika – this stood out as being the most northerly visitor I’ve had.

Welcome – and please leave a comment and introduce yourself!

Carbon Neutral flights

Sounds crazy – flying without incurring the cost of CO2 emissions.

However – I found an interesting website that helps calculate the ‘carbon cost’ of flying and the remedy to neutralise that usage.

The example given – for a medium haul flight – is something I do on a weekly basis. For example a round trip from Salt Lake to New York. To counteract this I need to purchase two trees. Or about five trees per month. That’s over fifty trees per year. Ouch.

You can calculate your own impact here.

rtfm?

It’s a long weekend – so fun with servers.

I wanted to replace the Windows 2003 server that hosts my Active Directory and Kerberos pieces – with a newer server running pretty much the same. I ended up using Windows 2003 R2.

Foolishly I assumed that ‘Windows 2003 R2’ == ‘Windows 2003 SP1’ and a few features. Nope.

Classic case of rtfm.

For those that want to do this – make sure you update the Active Directory Schema on the Windows 2003 servers before running dcpromo on the 2003 R2 server. Otherwise you’ll not get anywhere fast – and there is not a lot documented.

Here’s my find:

Update the Active Directory schema on domain controllers. In Windows Server 2003 Active Directory networks, you will need to update the Active Directory schema before:

• Installing Windows Server 2003 R2 on a domain controller.
• Configuring a Windows Server 2003 R2 server to be a domain controller by using the Active Directory Installation Wizard (Dcpromo.exe).

To update the schema, on the schema master domain controller, insert Disc 2 and open the command prompt. Then, change to the CmpnentsR2Adprep folder of Disc 2, and type: adprep.exe /forestprep

Right there in the docs. RTFM as I said.
