Event ID 4862 — COM+ General Functionality

  • Article

Applies To: Windows Server 2008

COM+ applications use Microsoft Component Object Model (COM) technology in Microsoft Windows operating systems to communicate and take advantage of Windows services. COM technologies include COM+, DCOM, and ActiveX Controls.

Event Details

Product: Windows Operating System
ID: 4862
Source: Microsoft-Windows-Complus
Version: 6.0
Symbolic Name: ID_E_CONVERSATION_DB_ERROR
Message: You have attempted to use COM+ Conversation support, and an error was generated accessing the database.

Resolve

Contact the application developer

The event message indicates that the error condition results from a problem in the application code. However, there is not enough information to provide a recommendation for resolution of the problem. Provide the entire event message to the application developer for debugging and fixing the application.

If the application is still running, recycle the process and then restart the application to resolve the error.

To perform these procedures, you must have membership in Administrators, or you must have been delegated the appropriate authority.

To recycle the process:

  1. Click Start, and then click Run.
  2. To open the Component Services snap-in, type comexp.msc, and then click OK. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  3. Click Component Services, click Computers, and then click My Computer.
  4. Under Running Processes, right-click the running process that you want to recycle, and then click Recycle.

To restart the application:

  1. In Component Services, under Component Services, click Computers, click My Computer, and then click COM+ Applications.
  2. Right-click the application that you want to restart, and then click Start.

If you continue to get this error, provide the entire event message to the application developer so that the developer can debug and fix the application.

Verify

You can verify that your COM+ application is installed and working properly by using the Component Services administrative tool.

To perform these procedures, you must have membership in Administrators, or you must have been delegated the appropriate authority.

To open Component Services and verify that your application is installed:

  1. Click Start, and then click Run.
  2. Type comexp.msc, and then click OK. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  3. To locate your application, click Component Services, click Computers, click My Computer, and then click COM+ Applications.

In addition, you can verify that the COM+ operating system component is installed and working properly.

To verify that COM+ is working properly:

  1. In the console tree of Component Services, click Services (Local).
  2. Scroll through the list of service names to find the following services: COM+ Event System (optional), COM+ System Application, DCOM Server Process Launcher, and Remote Procedure Call (RPC).
  3. Confirm that the status of each service is Started.
