SYMPTOMS
When you configure Microsoft Internet Information Services (IIS) virtual roots, and you use Interactive User as the COM+ program identity in Microsoft Windows XP Service Pack 2 (SP2) or in Windows XP Tablet PC Edition 2005, you may receive the following error message:

 * 2) Double-click Component Services.
 * 3) In the Component Services dialog box, expand Component Services, expand Computers, expand My Computer, and then expand COM+ Applications.
 * 4) Right-click your COM+ package, click Properties, and then click the Identity tab.
 * 5) Under This application will run under the following account, click This user:, specify the User, Password, and Confirm Password fields, and then click OK.
