When was the last time you got that not too friendly message stating that your password has expired and asking you to change it? Probably only a few weeks ago, and just as sure as day follows night, it is going to appear again only too soon. At least that is the typical user’s point of view. Security conscious administrators see this differently: they seem to think that passwords become weaker over time, like human beings growing old, and therefore force a rejuvenation process every couple of weeks. But is that really necessary? I do not think so. Continue reading ‘How Forcing Password Changes Actually Weakens Security’

Even with the most meticulous design, the day will come when your farm’s capacity is not sufficient any more. User numbers increase, applications become more resource-hungry and the amount of data to be handled increases steadily. So what do you do? Simply more of the same, i.e. buy more servers and add them to the farm? That is one way of increasing capacity, but it is not the only one and therefore may not be the best.

Jim Moyle recently started a blog on desktop and application delivery. While reading his first two posts I thought “yes, that’s so right“. Regretfully, people like him, who disregard the current hype and cut through the marketing BS, are scarce. More of the same, please!

Do you like what you read in this blog but have questions I did not answer (yet)? Or do you prefer listening and talking to live human beings instead of sitting alone in front of your screen? Well, come hear me speak and tell me what you think! This summer I will be speaking at the following conferences (all in Germany and in German, I am afraid):
- Citrix TechEdge in Munich, June 15th
- \\ice:2009 in Lingen, August 22nd
- nrw conf 09 in Wuppertal, August 28th
The topics of my talks will be various aspects of 64-bit Windows (Terminal Services / Citrix, Architecture, Migration, …).
The subtle differences between 32-bit and 64-bit Windows present so many intricacies and pitfalls that even Microsoft employees seem to have trouble getting it right. I just stumbled upon a KB article that describes how to reset the hosts file to its original state. The topic alone is funny enough – it is not as if the default hosts file contained great amounts of data. An entry for localhost (IPv4 and IPv6) is all you need, and on Windows 7 / Server 2008 R2 not even that. But anyhow, there seem to be enough people asking MS support for this or they would not have troubled with creating a package (ResetHOSTSFileBackToDefaults.MSI) that basically empties the hosts file.
