For a little while now I’ve had an irritating problem with my Vista laptop. Whenever I insert a DVD, CD of any kind, pops up the message asking me to prepare a blank disk: It’s impossible to access the files on the disc and I don’t want Vista trying to “prepare” my data disc. Quite irritating, but not irritating enough to fix right away. Microsoft have a KB article about it, which has worked in some cases, but not in most.

If, like me, you enjoy a bit of design in your free time then I have a great site for you… Blog Spoon Graphics is a fantastic site, with loads of free vector graphics downloads that you can use in your designs. It’s also got some great tips and stuff on vector art - take a look! This is probably a little off-topic, but hey - I like this site! And no, I haven’t sold out, it’s not a sponsored link…I just like it!

So I was testing the configuration on my Exchange 2003 server in preparation for the roll out of some Windows Mobile devices when I recieved the following error: Outlook(R) Mobile Access is supported only on Microsoft(R) Exchange Server 2003. Currently your mailbox is stored on an older version of Exchange server. Please contact your system administrator for additional assistance. “That’s odd”, I thought, “I only have Exchange Server 2003 in my organisation, how can I have an older version of Exchange?

Recently I wrote a little utility for a client using the excellent Html Agility Pack to read and navigate through a HTML page, selecting the data that was needed and parsing it - basically a screen scrape. I downloaded the source, compiled it, added a reference to the dll in my project and tapped away for a few minutes and et voila, within a few minutes a working screen scrape. A fantastic library.

I needed to use PowerShell for something today on my Vista laptop, but was unable to install the file. I had the normal UAC permission required when I ran it, but then it failed with this error Installer encountered an error: 0x80070422 The service cannot be started, either because it is disabled or because it has no enabled devices associated with it. It turns out that you need to enable the Windows Update service in order to use an MSU file.

I thought this would be fairly common knowledge by now, Exchange 2003 being quite mature in it’s 5th year, but it’s not something I’ve had a problem with before and therefore I’m going to write about it! So a big email comes in; lets say it’s 8MB. Your Exchange 2003 server, set to it’s defaults for size restrictions, rejects the email. Why? Take a look at this Exchange TechNet article:

We have a Bonded ADSL solution for our servers to provide the necessary upstream transfer speeds for the applications we host. We have bonded ADSL because our exchange still doesn’t support SDSL, and a leased line is overkill. Theoretically, we should have 28.1 Mbps download and 3.2Mbps upload - what I am actually seeing is about 1.7Mbps down and 1.9Mbps up. I have tested this on various servers, over various times and file sizes, there is no doubt that the performance is POOR.

Outlook Web access is a fantastic tool for our company, providing on-the-go access to people’s mailboxes - which is of course secured by SSL and uses Forms Based Authentication. Internally, we have an intranet portal that allows us to access the various systems - one of which is OWA. One of the stipulations for this internal portal is that it is all Single Sign On using NTLM authentication integrated authentication.
