There are some file properties that aren’t too easy to change. Neither in the command line or in Windows Explorer. One that I’ve wanted to change personally quite often is the created and changed dates of a specific file, or a batch of files. Background...

Today I found the following e-mail in my inbox: Hello According to this article, http://blogs.msdn.com/b/johan/archive/2008/01/31/using-windbg-hunting-exceptions.aspx written by you, you write that there are three "ever-present exceptions", I can see...

It’s been quite a while since I had the time to post. A customer dropped me this question today and I thought it’d be interesting to share. He wanted to change the “Allow rules to specify another site as a target location”-setting...

Yesterday I tried opening up a standard dump file from a 64-bit Windows 2008 Server. It opened up just fine in windbg, but when I tried executing a command I got the following: 0:000> !dumpheap -stat The garbage collector data structures are...

The problem I came across the following scenario a while back: A customer was creating a custom WebControl in the Visual Web Designer. The control had a smart tag panel with an option that they wanted to behave like a radio button. I.e. The text says...

Problem If you have a web application that uses SSL and this application, for some reason, is hosted on an IIS that doesn’t have Internet access you will eventually find that any call to the server over SSL will take a lot of time to reply. It doesn’t...

A customer called in the other day and told me that his web application took a long time to start. My initial thought was (off course) that it was a matter of the classic slow-to start web services I’ve written about earlier. ( What to do about the slow...

Consider the following scenario: You have an ASP.NET application which intermittently responds sluggishly. As the problem occurs memory usage is about average, as is CPU usage, but still certain pages respond slower and slower. The machine acts just as...

A recent case I worked on involved the following scenario. Problem description The client was building a kiosk-like application. I.e. a WinForms application with the WebBrowser control slapped onto it. The application worked fine for the most part, but...

In a recent case I was involved with I stumbled upon something quite interesting. The customer had set up a brand new Windows 2008 Server running IIS, and made it into a Read Only Domain Controller (RODC). Having done this they now wanted to add the FTP...

I've finally had the time to sit down and create a simple game for my Zune. Rather than running off and creating a complex game requiring a lot of AI, etc I wanted to create a simple application so that I could focus on the XNA-specifics. I decided to...

Today we release Internet Explorer 8. You'll be able to download it later today from http://www.microsoft.se/ie8 / Johan

Stephen Elop, the president of Microsoft's Business Division recently held a presentation where he allowed the viewers to glimpse 10 years into the future. It's amazing to look at a "real" interpretation of the future interfaces and technologies...

It's been fun to see the reception that PowerShell has gotten. People are using it for tons of different stuff and the ingenuity in some of the scenarios is quite impressive. There is one thing, however, that you should be aware of. PowerShell is not...

Perhaps you've read my earlier post on advanced feature delegation using PowerShell and the IIS 7.0 PowerShell Provider . This could actually be called Part II. The previous post was based on a quick question from a premier customer. He is a never-ending...

A very common scenario that keeps sprouting new heads like a hydra is Office Automation. Let me start by saying that this is not supported. There is a KB-article number 257757 discusses this, and clearly states the following: Microsoft does not currently...

I've written a lot of PowerShell posts lately and here's another one. :-) I got a question from one of the account managers if it was possible to alter the FTP Authorization Rules for a specific folder on his IIS. The appcmd for the operation was appcmd...

I got the following question from a reader the other day: I've been trying to figure out how to change permissions on a folder in PowerShell. I've looked at the Get-Acl and Set-Acl, but I can only use them to copy the settings from a pre-existing object...

Is your mp3-collection perfectly sorted? I know mine wasn't. I thought I'd address that while creating a pretty good demo-script to show some basic filtering, script structures, etc. Since I also wanted the script to extract the metadata from every file...

This is a continuation of part I . If you haven't read it I suggest at least going through the summary at the end of the post. Working with Drives In your basic command prompt you have the normal file system drives that you use to access your hard-drive...

Okay, after a summer break that no doubt got a little longer than expected I am now I'm now back in the saddle again. Next post will most likely be a follow-up on the PowerShell post I wrote a while back. Stay tuned. / Johan

As you're probably well aware IIS7 relies heavily on a master configuration file named ApplicationHost.config. Now, instead of using a history file like IIS6 did, IIS7 will check this file every 2 minutes to see if it's changed. If the file has been updated...

Over the past months I’ve been holding a couple of workshops on PowerShell. It’s quite an interesting topic, but not something I originally thought would be suitable for this blog and its web-development theme. Still, having given this a bit more thought...

I got the following question in my Getting started with windbg – post and I thought it might be worth posting the replies in a separate article: Hi Johan, about those threads with an ID of XXXX, should they go away after certain amount of idle time like...

Due to the architecture of web services and web applications they can be quite slow to start. For example on my Windows 2003-box the initial localhost-call to a simple “Hello World!”-web service takes approximately 8 seconds, while the next request is...
