WSS 3.0 SP2 Upgrade failed with an error message - Action 3.1.3.0 of Microsoft.SharePoint.Upgrade.SPIisWebSiteWssSequence failed

Applying Service Pack 2 failed with an error message. Observed the following details from the upgrade.log file.

When we narrowed down the error we came to the conclusion that Upgrade failed due to deletion of some Application Pools. There is no UI in SharePoint to change Application Pool of a web application.

 

In my case, we reappointed the Application Pools, as per their previous state of the web applications to reach a quicker resolution. However, it is a good practice to delete the respective Web Application &  Application Pool and create a new one.
