Application Isolation Mode Defaults (IIS 6.0)
When you install IIS 6.0 on a computer that does not contain an earlier version of IIS, IIS 6.0 automatically sets the application isolation mode to worker process isolation mode. If you upgrade from a earlier version of IIS, IIS 6.0 sets the application isolation mode to IIS 5.0 isolation mode.
Table 2.3 lists the IIS 6.0 default settings for the two application isolation modes.
| Table 2.3 Default IIS 6.0 Installation Settings for Each Application Isolation Mode | |
| Type of Installation | Application Isolation Mode |
New installation of IIS 6.0 (clean install) | Worker process isolation mode |
Upgrade from an earlier version of IIS 6.0, such as a beta release | No change in isolation mode |
Upgrade from IIS 5.0 | IIS 5.0 isolation mode |
Upgrade from IIS 4.0 | IIS 5.0 isolation mode |
Although IIS 5.0 isolation mode is the default application isolation mode when you upgrade from earlier versions of IIS, be sure to test your applications for compatibility issues so that, if possible, you can upgrade to worker process isolation mode.
