Error Resolution For COM Error For Sharepoint Application on Windows Server 2008 64 Bit

Hello Friends

Retrieving the COM class factory for component with CLSID {BDEADEE2-C265-11D0-BCED-00A0C90AB50F} failed due to the following error: 800703fa

We have noticed that this error occurs only on SharePoint 2007/Windows 2008 64 Bit server. The error pattern is kind of strange, application will work fine initially and then intermittently server will start throwing "COM Class factory" Error. As of now we did not find any set of steps to reproduce this error. The only quick resolution we have found during research is to perform IISRESET and error will go away. The Error will again reappear after 1-2 days. Finally after opening case with Microsoft support and extensive research we got the resolution. Please follow the steps –

1.       To open IIS 7 Manager from the Start menu

1.   Click Start, and then click All Programs.

2.   Click Administrative Tools, and then click Internet Information Services (IIS)    Manager.

3.   To open IIS Manager from the Search box

4.   Click Start.

5.   In the Start Search box, type inetmgr and press ENTER.

2.   Access Application Pools within IIS manager. Find and select “Application Pool” for your  SharePoint application. 

3.   Click “Advanced Settings” from Actions menu. You will be presented with settings window. Find “Load User Profile” settings under “Process Model” section. By default the value is set to “False”. Change it to “True”.

4.   Click “OK” to save the settings. Exit IIS manager from File->Exit.

5.   Changing Load User Profile setting from FALSE to TRUE will stop Intermittant COM errors.
