The information in this article applies to:

- Microsoft Internet Information Server versions 4.0, 5.0 
- Microsoft COM+, version 1.0 
- Microsoft Transaction Server 2.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When users access an application from an Active Server Pages (ASP) page, the
application may fail if there is no user logged on to the Internet Information
Server (IIS) console. The client computer returns the following error message:

  HTTP 500 Internal server error

  -or-

  Server Application Error The server has reached the maximum recovery limit
  for the application during the processing of your request. Please contact the
  server administrator for assistance.

The following error appears in the event log on the server:

  The server stop serving requests for application '/LM/W3SVC/1/Root/Test'
  because the number of Out of Process component crashes exceed a limit.

CAUSE
=====

The identity for the COM+ application or the Microsoft Transaction Server (MTS)
package is configured for "Interactive user - the current logged on user".
Because no user is currently logged on to the IIS console, the application
cannot run.

RESOLUTION
==========

To resolve this problem, set the identity for the COM+ application or the MTS
package to "This User", and specify a user account. See the "More Information"
section for the step-by-step procedure.

MORE INFORMATION
================

How to Set the COM+ Application Identity on IIS 5.0:

1. On the Start menu, point to Programs, point to Administrative Tools, and then
  click Component Services.

2. Click to expand the Component Services, Computers, My Computer, and COM+
  Applications nodes. Locate the application whose identity you want to
  change.

  If you are not sure which application to modify, check the properties of the
  Web site (or virtual directory) where your ASP application resides in the
  Internet Services Manager.

  On the Home Directory or Virtual Directory tab, check the Application
  Protection setting:

  a. If the default Medium (Pooled) setting is selected, you should modify the
     IIS Out-of-Process Pooled COM+ Applications application identity in
     Component Services.

  b. If High (Isolated) is selected, you should modify the COM+ application
     that has the same name as your Web site.

  c. If Low (IIS Process) is selected, the site is running in the IIS memory
     space. This service is running under the local system account and cannot
     be modified through the IIS snap-in.

3. Right-click the appropriate COM+ application, and then click Properties.

4. On the Identity tab, click This User, and type a valid account for the
  computer. Click OK to apply the changes.

How to Set the MTS Application Identity on IIS 4.0:

1. Start the Internet Service Manager.

2. Click to expand the Computers, My Computer, and Microsoft Transaction Server
  nodes. Locate the package whose identity you want to change. The application
  is listed under the Packages Installed folder.

  If you are not sure which application to modify, check the properties of the
  Web site (or virtual directory) where the ASP application resides under
  Internet Information Server.

  On the Home Directory or Virtual Directory tab, check the Run in separate
  memory space check box:

  a. If the check box is selected, the name of the package is the same as the
     name of the site.

  b. If the check box is not selected (which is the default setting), the site
     is running in the IIS process and cannot be modified.

3. Right-click the package, and then click Properties.

4. On the Identity tab, click This User, and type a valid account. Apply the
  changes.
