Hosting ASP applications in IIS 7
Today I needed to configure IIS 7 to host an old classic ASP application. I was facing a permissions problem when i tried to access an Access DB (which persisted even after I've given full control to the directory where the ASP application was installed). I was able to solve this problem after giving permissions to the temp dir of the network service account. This Kb gives you all the info you need on this.
