Configuring Application Isolation Settings in IIS 5.0 Isolation Mode

  • Article

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

When the target Web server is configured to run in IIS 5.0 isolation mode, configure the application isolation settings on the target server identically to the settings on the source server. Web sites and applications on a Web server running in IIS 5.0 isolation mode can be configured with the following application isolation settings:

  • Low (in-process).

  • Medium (pooled).

  • Low (isolated).

If the identity on the source server is an account local to the source server, you need to create a service account.

Configure the application isolation settings when IIS 6.0 is configured to run in IIS 5.0 isolation mode by completing the following steps:

  1. Review the application isolation settings on the source server, documented earlier in the migration process.

    For more information about how the application isolation settings were documented, see Documenting the Current Application Isolation Settings on the Source Server.

  2. Create any required local service accounts used for application isolation identities on the target server.

    When the application pool identity is a service account that is local to the source server, you need to create a new service account, or designate an existing service account, on the target server. Create the service account in Active Directory to:

    • Provide centralized administration of the account.

    • Provide stronger security because the account is stored in Active Directory rather than locally on the Web server.

    • Allow more than one Web server (for instance, in a Web farm) to use the same service account for the same instance of the application pool on other Web servers.

    For more information about how to create a service account to be used as an identity, see Create a Service Account.

  3. Configure the application isolation settings for the Web sites on the target server to be identical to the settings in Step 1.

    For more information about how to configure the application isolation settings for a Web site, see Configure Application Isolation Settings for IIS 5.0 Isolation Mode.

  4. Configure the application process identities for the Web sites on the target server to be identical to the settings in Step 1.

    For more information about how to configure the application process identities for the Web site, see Configure Application Identity for IIS 5.0 Isolation Mode.
