Configuring IIS 6.0 to Run in Worker Process Isolation Mode

Applies To: Windows Server 2003, Windows Server 2003 with SP1

As previously mentioned, configuring the IIS application isolation mode is a Web server-wide configuration setting that affects all Web sites and applications running on the Web server. The server is currently configured in IIS 5.0 isolation mode.

If you determined that one or more of your Web sites or applications are incompatible with worker process isolation mode, leave the Web server in IIS 5.0 isolation mode. Otherwise, configure IIS 6.0 to run in worker process isolation mode either in IIS Manager, or by setting the IIS metabase property IIs5IsolationModeEnabled to a value of False.

Note

If you configure IIS 6.0 to run in IIS 5.0 isolation mode and then decide to change the configuration back to worker process isolation mode, the original worker process isolation mode settings are retained. Similarly, if you configure IIS 6.0 to run in IIS 5.0 isolation mode, change to worker process isolation mode, and then change back to IIS 5.0 isolation mode, the IIS 5.0 isolation mode settings are retained.
