A few months back decided to try out Visual Studio 2010 which uses version 4 of the .NET Framework. So I proceeded to install everything and after a few reboots everything was done. However my boot process was no longer showing me its race cars and rockets. No, it was more like turtles and slugs. The startup application loading process would stop halfway for about 2 minutes and after that everything would start loading again. What was weird was that the windows firewall built-in to Windows XP, my anti-virus, and networking all would not load. Of course after the initial 2 minutes of wondering whether Iâ€™m going to have to install the OS `again`, everything proceeded normally. So I did what I normally do when things act up. Which is dig in the forums, blogs, and general internet. Eventually I found on my own that the new version 4 of the NGEN service was to blame. For some reason it was failing to load or something and was holding everything else up in the process. After googling some more and turning up empty I decided to just disable the NGEN service at startup, only starting it after everything else had loaded.
Recently I found some new forum posts from August that described using the command â€œngen updateâ€ from the directory â€œC:\Windows\Microsoft.NET\Framework\v4.0.30319\â€. After waiting for what seemed like forever, I set the NGEN v4 Service back to Auto so it would start at the next boot. I rebooted and logged in and to my amazement everything was fixed. No disabled firewall or anti-virus and the network was immediately available. It ran just like it was before when the service was disabled but without the 2 minute wait times. So Iâ€™m very happy to have this problem fixed. Just another bug and another day.
