Delegated Administration

By Walter Oliver

December 1, 2007

The IIS 7 and above administrative user interface, called the IIS Manager, offers a more efficient tool for managing the Web server. It provides support for IIS and ASP.NET configuration settings. It also lets those who host or administer Web sites delegate administrative control to developers or content owners, thus reducing cost of ownership and administrative burden for the server administrator. It supports remote connections over HTTP, and you can use it through a firewall.

For more information about the administration features in IIS, see Delegating Administration.

Before enabling remote delegation, you should consider what features and properties you want to delegate to site owners.

The following table lists a sample set of features, their delegated settings, and reasons to delegate or not on the Web server. Based on the shared hosting environment that you use, you should develop your own set of delegated features that meet your needs.


  1. Some of these features may not appear in the list of features to manage if you have not installed them. For example, if you chose not to install Digest authentication, it will not appear in the list on your Web server.
  2. There will be cases when you want to delegate a particular setting in applicationhost.config without delegating an entire section, here are two key examples:
    1. Delegating errorMode in httpErrors
    2. Delegating scriptErrorSentToBrowser in ASP


Delegated Setting


.NET Compilation

Read Only

(changed from Read/Write)

Specifies settings for ASP.NET compilation processing directives such as the temporary compilation directory.

Prevents users from setting the temporary compilation directory manually.

.NET Globalization

.NET Roles

Configuration Read/Write

Specifies the settings for groups for use with .NET users and forms authentication.

.NET Trust Levels

Read Only

(changed from Read/Write)

Specifies the trust level. By locking down the trust level when you follow the ASP.NET guidance in this document, you will set this to Read Only and locking it for the server.

Prevents Web site owners from setting the trust level to a higher level than that set by the server administrator. For example, if the administrator sets a custom trust level, make this setting Read Only so it cannot be overridden.

.NET Users

Configuration Read/Write

Specifies the settings for management of users who belong to roles and that use forms authentication.

Application Settings


Specifies the settings for storing data (name and value pairs) that managed code applications use at runtime.


Read Only
