While starting development on a new project in Windows 7, I ran across the following error when trying to access the database.

Cannot open database "" requested by the login. The login failed.
Login failed for user 'IIS APPPOOL\DefaultAppPool'.

I initially Googled the error and found this forum post that helped me solve the problem. The site is in some other language so I will go over what you need to do here.

First, find the site that your application running under in IIS.

Select the site and click on “Advanced Settings” in the column on the right. See which Application Pool your site is running under.

Now, click on “Application Pools” in IIS and select the application pool that your site is running under. Click on “Advanced Settings”.

Scroll down to the “Process Model” section and click on the identity field. Once it is selected, click on the “ellipsis” button. In the dropdown under “Built-in Account” select “LocalSystem”.

First!

I set this site up a few months ago intending on making some posts, but never got around to doing it. I would like to use this blog to post about interesting things I find related to technology. The topic could cover programming, software, hardware, or anything else related to technology. I may throw in a few personal posts here and there just to mix things up.

The first post should come shortly about a little jQuery extension I wrote for work.
