SYMPTOMS
If you use the Internet Services Manager to manage your Microsoft Internet Information Server (IIS)-based computer, you may receive the following error message:

Error reading IIS default vroot info

Error 3005F

Unable to read configuration for Microsoft Internet Information Server

OS error number -2147024891

Access is denied



CAUSE
The virtual servers may be running at an isolation level other than the default for your version of IIS.



RESOLUTION
To resolve this issue, you must configure each virtual server to use the default isolation settings for your version of IIS.

In IIS 4.0, the default isolation setting is Low, also known as running in separate memory space (isolated process). In IIS 5.0, the default isolation setting (also known as Application Protection), is Medium.

To set the isolation setting to Low in IIS 4.0, follow these steps:
 * 1) Click Start, click Programs, click Windows NT 4.0 Option Pack, click Microsoft Internet Information Server, and then click Internet Service Manager.
 * 2) In the management console, double-click the Internet Information Server folder, and then double-click the computer node.
 * 3) Right-click the Default Web Site, and then click Properties.
 * 4) Click the Home Directory tab.
 * 5) Click to clear the Run in separate memory space (isolated process) check box, and then click OK.
 * 6) Repeat steps 3 through 5 for each Web site that is configured.
 * 7) Close the Internet Information Services management console.

To set the Application Protection setting to Medium in IIS 5.0, follow these steps:
 * 1) Click Start, click Programs, click Administrative Tools, and then click Internet Services Manager.
 * 2) In the Internet Information Services management console, double-click the computer node.
 * 3) Right-click the Default Web Site, and then click Properties.
 * 4) Click the Home Directory tab.
 * 5) In the Application Protection item list, click Medium (Pooled), and then click OK.
 * 6) Repeat steps 3 through 5 for each Web site that is configured.
 * 7) Close the Internet Information Services management console.
