SYMPTOMS
When you browse a Windows SharePoint Services 2.0 Web site, you may receive the following error message:

Service Unavailable



CAUSE
This issue may occur if the application pool for the virtual server is configured incorrectly in Microsoft Internet Information Services (IIS) 6.0. This issue may occur if one or more of the following conditions are true:
 * The application pool is not running.
 * The application pool account uses an incorrect password.
 * The application pool account is not a member of both the IIS_WPG group and the STS_WPG group on the server.



RESOLUTION
To resolve this problem, follow these steps:  Verify that the application pool is configured for the virtual server. The default application pool is MSSharePointPortalAppPool.

Follow these steps to determine the application pool that the virtual server is using:  Click Start, point to Administrative Tools, and then click Internet Information Services (IIS) Manager. Expand  , expand Web Sites, right-click the virtual server, and then click Properties. Click the Home Directory tab.

The application pool that is configured for the virtual server is listed in the Application pool box. Click OK. </li> Verify that the password for the application pool account is correct. IIS does not automatically poll password changes in Active Directory directory service. If the application pool account is a domain account, and the password expires, you may receive the error message that is described in the &quot;Symptoms&quot; section of this article after a new password is specified for the account.

Verify that both IIS_WPG and STS_WPG appear in the Member of list. If one or both groups are not listed, add the IIS_WPG group, the STS_WPG group, or both groups (as appropriate) to the list.</li></ol> </li> If Windows SharePoint Services 2.0 is installed on a domain controller: <ol> <li>Start Active Directory Users and Computers.</li> <li>Expand Users.</li> <li>Right-click the account that is used by the application pool for the virtual server, and then click Properties.</li> <li>Click the Member of tab.
