Verify that the application pool is configured correctly for the virtual server.
Note The default application pool is MSSharePointPortalAppPool.
To determine the application pool that the virtual server is using, follow these steps:
Click Start, point to Administrative Tools, and then click Internet
Information Services (IIS) Manager.
Expand ServerName, 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.
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 "Symptoms" section of this article after a new password is specified for
the account.
To verify that the password for the application pool account is correct, follow these steps:
In Internet Information Services (IIS) Manager, expand
Application Pools.
Right-click the application pool that is configured for
the virtual server (for example, right-click
MSSharePointPortalAppPool), and then click
Properties.
Click the Identity tab.
In the Password box, type the password
of the application pool account that is listed in the User
name box, and then click OK.
In the Confirm Password dialog box,
type the password again, and then click OK.
Verify that the application pool account is a member of both the IIS_WPG group and the STS_WPG group on the server. To do this, use one of the following methods:
Method 1: Windows SharePoint Services 2.0 is installed on a member server
Click Start, point to
Administrative Tools, and then click Computer
Management.
Expand Local Users and Groups,
and then expand Users.
Right-click the account that is used by the
application pool for the virtual server, and then click
Properties.
On the Member of tab, 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.
Method 2: Windows SharePoint Services 2.0 is installed on a domain controller
Start Active Directory Users and
Computers.
Expand Users.
Right-click the account that is used by the
application pool for the virtual server, and then click
Properties.
Click the Member of tab. 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.
Restart IIS to recycle the application pools:
In Internet Information Services (IIS) Manager,
right-click ServerName, point to All Tasks, and then click Restart
IIS.
Click Restart Internet Information Services on ServerName, and then click OK.
